This study presents a comprehensive investigation into the influence of crack inclination, length, and location on mechanical behavior, damage characteristics, and energy evolution in rocks. The findings demonstrate that the closed cracks significantly alter the stress–strain. The peak strength and elastic modulus exhibit an asymmetric U-shaped variation with increasing crack angle, decreasing quadratically with increasing crack length, and the crack location also affects the mechanical properties. Furthermore, the inclination angle and location of closed cracks considerably affect the damage characteristics. Cracks near the upper boundary of the specimen are less likely to propagate. Regarding energy evolution, this study presents a novel method using the residual energy index to assess the impact characteristics. The residual energy index initially decreases and then increases with increasing crack inclination. The residual energy index initially decreases and then stabilizes as the crack length increases, with the critical crack length identified as 15 mm.

The time-dependent behavior of these structures has been observed to be significantly impacted by the development of excavation-induced fractured zones around the drifts. A numerical model is proposed to simulate the response of drifts excavated in various conditions and the obtained results are compared to in-situ data. This model is based on the explicit introduction of an anisotropic excavation-induced fractured zones following the extension observed in situ and the implementation of a visco-elasto-plastic model (CVISC) for the rock mass using the FLAC3D numerical code. The model reproduces the anisotropic distribution and evolution of the rock mass deformation, which tends to accumulate within the excavation-induced fractured zones. The influence of the extension of the fractured zone on the response is investigated through a sensitivity analysis. It shows that the variability of the measured convergence data can be reproduced by using fractured zone extensions that are consistent with the ones observed in situ. Also, various support scenarios are modeled. Flexible supports lead to low radial confinement levels, while stiffer supports provide greater confinement, significantly reducing the strain rates in the rock mass. The model is able to simulate multiple drift configurations and orientations using a simple approach and accurately reproduce the field observations. This suggests that this approach is a useful tool for designing tunnels excavated in COx claystone and for evaluating the long-term response.</div></div>","PeriodicalId":55217,"journal":{"name":"Computers and Geotechnics","volume":"179 ","pages":"Article 107030"},"PeriodicalIF":5.3,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144405","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}

However, efficient analytical methods for such extreme temperature ranges are lacking. To address this challenge, we propose a thermo-mechanical coupling Distinct Lattice Spring Model (DLSM) based on computerized tomography (CT) and X-ray diffraction (XRD) analyses. This approach enables the modeling of rock structures by integrating CT imaging with XRD mineral composition analysis, accounting for factors like pore distribution, porosity, ice saturation, mineral composition, and their corresponding strength distributions. By embedding this model into the thermo-mechanical DLSM, thermal damage simulations can be performed. The proposed method is validated through analytical solutions and experimental results, demonstrating its reliability. Parametric simulations were conducted, leading to several key conclusions. For low-porosity sandstone, the damage variable exhibits minimal change with temperature or saturation. Conversely, for high-porosity sandstone, temperature significantly influences damage. In the early cooling stage, the damage variable decreases sharply, while in later stages, the decrease is more gradual. The damage variable shows slight decreases with saturation and porosity but drops significantly after reaching critical thresholds for both. The study reveals further cooling damage mechanisms, including the effects of mineral shrinkage, ice expansion, temperature, porosity, and saturation. The weakening of damage with decreasing temperature is attributed to stress concentration relief and the reduction in the absolute coefficient of thermal expansion.
