This study examines how joint roughness (JRC 2.8–16.76), infilling ratios (0–2), and normal stresses (0.5–8 MPa) affect shear behavior. Specimens were sheared at 0.6 mm/min while monitoring acoustic emissions to track strength changes and failure patterns under four normal stress levels. Results demonstrate that increasing infilling ratio significantly reduces peak shear strength, residual strength, dilatancy, and shear modulus, with the weakening effect intensified by higher roughness. While roughness enhances shear resistance, its mechanical contribution is counteracted by elevated infilling ratios. A novel tripartite framework reveals the synergistic interplay of three components governing shear strength: roughness-dependent asperity degradation, infill material strength, and rock-fill interface bonding. The dominance of these components shifts dynamically with infilling ratio—roughness effects diminish as infilling dominates, whereas infill and interface contributions rise but are constrained by asperity interactions. Normal stress further modulates this balance by promoting infill compaction while suppressing interface effects. AE analysis corroborates the transition from asperity-driven to infill-controlled failure, marked by reduced shear-induced energy release and altered crack mode dominance. These findings establish a mechanistic basis for evaluating shear behavior in rock masses with heterogeneous infilling, offering theoretical insights for stability assessment and reinforcement design under complex geological conditions.</div></div>","PeriodicalId":54941,"journal":{"name":"International Journal of Rock Mechanics and Mining Sciences","volume":"193 ","pages":"Article 106167"},"PeriodicalIF":7.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144167208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case study investigates fracture hydrology at the Beishan Exploration Tunnel, a key field platform for China's HLW repository in crystalline rock. A series of field investigations were conducted in six strategically positioned vertical boreholes intersecting faults. Methodologies included core logging, borehole acoustic televiewer logging, slug interference tests, natural gradient tracer tests, and dipole tracer tests. These integrated approaches were employed to assess critical hydrological parameters such as hydraulic conductivity, natural flow direction, inter-borehole hydraulic connectivity, and transport properties. The investigations identified two distinct sets of visible fractures. Slug interference tests provided hydraulic conductivity estimates for the boreholes, and inter-borehole hydraulic connectivity was evaluated using a proposed Hydraulic Connectivity Coefficient index, the centrally located borehole (A2-3) exhibiting the strongest connectivity. Natural gradient tracer tests established groundwater flow from borehole A2-5, through A2-3, to A2-1. Dipole tracer experiments, coupled with normalized mass flux data fitting, yielded key transport parameters including the number of flow channels, channel length, dispersivity, Darcy velocity, and tracer recovery rates.

The influence of temperature and thermal cycles on the physical and tensile mechanical properties, failure process, and morphological characteristics was analyzed, and the coupled failure mechanism was discussed in combination with numerical simulation. The results show that the P-wave velocity and dynamic tensile strength of granite decrease with increasing CTS temperature and cycles, while porosity increases, and a response surface model for the degradation of physical properties is developed. The central cracking of the FBD specimens is controlled by pure tensile, and the cracking time lags with increasing CTS temperature and cycles. The specimens exhibit tensile-shear composite failure, and the failure forms change from Y-shape to X-shape with increasing temperature, but transition from Y-shape to mono-diagonal shape with increasing thermal cycles. The fractal dimension and joint roughness coefficient (<em>JRC</em>) of the fracture surface are positively correlated with CTS temperature and cycles. Moreover, the CTS-induced thermal cracks increase with temperature and thermal cycles in a polynomial and negative exponential function law, respectively, making the granite transgranular fracture more prominent.

A critical aspect of this technique is the interpretation of the shut-in pressure to ascertain the magnitude of the minimum principal stress. Existing interpretation methods primarily focus on the pressure decay rate or its simple transformation, and an effective physical model has not yet been established to quantitatively characterize the crack closure process, resulting in a certain degree of ambiguity in determining the shut-in pressure. This paper introduces a new approach of determining shut-in pressure based on the Total System Stiffness (TSS). The objective of the TSS method is to better account for fracture responses by decomposing the pressure decay rate and estimating fluid leakage volume, thereby converting the pressure decay curve into a total system stiffness curve. The performance of this method is rigorously evaluated through comparisons with existing methods, utilizing several shut-in curves obtained from field HF experiments. The results demonstrate that the TSS method can serve as a feasible alternative for determining shut-in pressure. The variations of total system stiffness following shut-in can be divided into three main stages, the characteristics of which may be used to identify the upper and lower bounds of shut-in pressure. The primary advantage of the proposed TSS method is that it provides clear physical interpretations for both the beginning and end of the fracture closure process. Consequently, shut-in pressure determined by this method exhibits reduced sensitivity to time window selection compared with conventional approaches. Moreover, the TSS method relies solely on the pressure data, without any fitting or extrapolation. The TSS method is anticipated to have a wide range of applications for the analysis of in-situ stress associated with hydraulic fracturing.</div></div>","PeriodicalId":54941,"journal":{"name":"International Journal of Rock Mechanics and Mining Sciences","volume":"192 ","pages":"Article 106160"},"PeriodicalIF":7.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In deep formations with high gas content and low permeability, variations within coal pore structure influence methane extraction efficiency. This study explores the dynamic regulatory mechanisms influencing flow anisotropy in coal pore structures across varying degrees of metamorphism. The nonlinear responses of flow capacity and transition phenomena under different gas pressure conditions have been investigated using fluid intrusion methods, digital core technology, and numerical simulations. The results show that the interdependent coal pore parameters create anisotropic structures, with gas flow capacity initially decreasing and then gradually increasing with rising pressure differences. This nonlinear change may result from the dynamic adjustment of the internal pore structure, although some responses exhibit hysteresis. Low-rank coals exhibit four flow direction transitions within a pressure difference of 0.7–3.9 MPa, while high-rank coals demonstrate pore homogenization, characterized by high stability in flow direction without any transitions. The flow transition phenomenon in low-rank coals is attributed to the sensitivity of their loose molecular structure to pressure changes, whereas the dense structure of high-rank coals suppresses pressure response. These findings emphasize the impact of coal rank and pore interactions on flow behavior. Low-rank coals necessitate dynamic pressure regulation to capitalize on flow direction transitions, while high-rank coals require strategic placement following their inherently dominant direction.

A novel physics-informed neural network (PINN) is then developed to calculate the seismic acceleration induced by seismic waves. The PINN-based framework has the advantage of describing the spatiotemporal characteristics of seismic waves while adhering to the geometrical constraints of slopes. To acquire the space-dependent seismic force-generated work rates, a slice integration strategy is introduced, followed by the derivation of the stability number with seismic action. Determining the critical stability number of cracked rock slopes involves identifying a critical failure mechanism characterized by cracks that most adversely affect slope stability in terms of depth and location. This process is a multivariable optimization scheme supported by the innovative Marine Predators Algorithm (MPA). Results indicate that seismic excitation and the existence of cracks considerably narrow the stress distribution range on the Hoek-Brown strength envelope, leading to a reduction in rock slope stability. The PINN model can provide a more realistic distribution characteristic of seismic loadings within slopes, taking into account the slope geometry, rock properties, and seismic wave characteristics.
