Laboratory tests were conducted on specimens prepared with varying degrees of compaction (<span><math><mrow><msub><mi>D</mi><mi>c</mi></msub></mrow></math></span> = 75 % and 90 %), CMC concentrations (0.5 % and 1.0 %), and CS: CMC mixing ratios (1:1 and 2:1). The effects of biopolymer treatment were examined based on soil mechanics principles. In the oedometer tests, specimens with higher CS: CMC ratios exhibited greater consolidation yield stress and compressibility, whereas permeability decreased with the addition of biopolymer. Specifically, at a CS: CMC ratio of 2:1, the consolidation yield stress was approximately 2.5 times higher, and the compression index increased by about 1.3 times compared to unimproved soil. Additionally, the permeability coefficient was reduced to approximately 0.2–0.5 times that of unimproved soil due to the addition of biopolymer. In the triaxial compression tests, a higher CS: CMC ratio led to more pronounced hardening with plastic expansion and improved shear strength. For example, at CMC concentration of 1 % and <span><math><mrow><msub><mi>D</mi><mi>c</mi></msub></mrow></math></span> = 75 %, the maximum deviator stress for CS: CMC = 2:1 was approximately three times greater than that of the unimproved soil. These mechanical behaviours suggest an increase in overconsolidation ratio (OCR). Furthermore, the addition of biopolymers altered not only the soil skeleton structure but also fundamental physical properties such as the liquid limit and compression index, indicating a change in the “type” of soil itself. The upward shift of the normal consolidation line (NCL) caused by biopolymer treatment contributes to an increase in the OCR. These findings provide important insights into the mechanisms of biopolymer-based soil improvement from a geotechnical perspective, enabling the design of more efficient and sustainable soil reinforcement systems.</div></div>","PeriodicalId":56013,"journal":{"name":"Transportation Geotechnics","volume":"55 ","pages":"Article 101670"},"PeriodicalIF":5.5,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144829303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, the random dynamic load of vehicles on the roads in the construction area further complicates the assessment of ground surface deformation. To better understand such coupling effect in pipe-jacking tunnel construction, this paper combines the Strain-softening model with the FLAC^3D seepage-stress coupling module to simulate the whole process of pore water pressure migration, stress redistribution, grouting, and jacking. The accuracy of the numerical simulation results is verified through comparison with on-site monitoring data. The results show that the jacking process causes rapid dissipation of pore water pressure at the boundary of tunnels. This consequently induces a symmetrical distribution pattern of stress and strain fields about the boundary between extrusion and unloading zones. The maximum principal strain concentrates at the tunnels’ waistline. The seepage-stress coupling effect increases the settlement of the vault by 8.3 mm, while the uplift and horizontal displacement of the bottom arch decrease by 4.1 mm and 8.0 mm respectively. The sensitivity analysis of vehicle dynamic load reveals that the peak ground surface settlement increases by 12 % when the vehicle speed decreases from 80 km/h to 40 km/h. The rise of groundwater level significantly increases the value of ground surface settlement. A quantitative relationship is proposed to quickly predict the ground surface settlement under different groundwater levels, and the Peck’s settlement formula is revised in this paper. The error between the peak settlement and monitoring data is only 2.5 %, which is significantly better than the traditional superposition method. The contour map of safety factor shows that the soil overlying the left pipe-jacking is the weakest (FOS = 1.22), but the whole structure is still in a safe state.</div></div>","PeriodicalId":56013,"journal":{"name":"Transportation Geotechnics","volume":"55 ","pages":"Article 101671"},"PeriodicalIF":5.5,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil under train operation is subjected to the cyclic loads transmitted by the train track, which are different from constant or monotonically changing boundaries. The cyclic effect of train vibrations results in significant differences in the response of the seepage erosion around the tunnel. To investigate the combined effect of train vibration and seepage erosion on the mechanical responses of soils, the coupled computational fluid dynamics and discrete element method (CFD-DEM) was employed to study the behaviors of gap-graded soil during seepage erosion under different vibration frequencies (i.e., 10 Hz, 30 Hz, 50 Hz) and amplitudes (i.e., 0.1 mm, 0.2 mm, 0.4 mm). The results show that as the vibration frequency and amplitude increase, the effect of vibration on seepage erosion becomes more severe. The average increase of the loss of non-eroded fine particles all exceeded 25 %, and the average fine particle loss ratio reaches 84 % across all vibration conditions. The mechanism of the combined effect of train vibration and seepage erosion is revealed from the macroscopic and microscopic perspective, including fine particle distribution, particle and flow field velocity, coordination numbers, contact force, particle trajectory, and coarse particles pore structure. It is found that vibration affects the seepage erosion process mainly by disrupting coarse–fine particle contacts, whose loss of strong contacts in coarse–fine contact (C–F) exceeds 65 %. The higher the vibration frequency and amplitude, the faster the adjustment of the coarse particle skeleton structure, which is approximately 3 s faster than in no vibration case. Vibrations can affect the mechanical properties of the soil during seepage erosion by reducing the coordination number of particles and decreasing the proportion of strong contacts in coarse–fine particle contacts.

This study investigates hydrothermal dynamics within the active layer based on in situ experimentations of soil temperature and moisture collected from 2018 to 2023 along the Genhe–Labdalin Highway in the permafrost region of Inner Mongolia. The effects of climatic conditions and site-specific factors on hydrothermal dynamics and permafrost table variations are explored in detail. The main results are as follows: 1) The temperature and moisture in the embankment show periodical changes, and the moisture changes lag behind the temperature changes. The temperature and moisture fields of the embankment show lateral inhomogeneity, preferential flow paths appear underneath the embankment, and the internal moisture field of the embankment shows a concave shape. 2) The permafrost table of the embankment has been declining yearly. The asphalt pavement of the embankment and the wetland on the right side of the embankment, with the priority flow path underneath, accelerated the degradation of the permafrost, and the permafrost table of the embankment shows a concave shape. 3) Preferential flow paths of the embankment have a high capacity to transport moisture, accelerating the thawing of permafrost under the embankment for many years and severely affecting the stability and performance of the highway infrastructure. These findings reveal that preferential flow paths beneath highway embankments are closely linked to hydrothermal variations and are strongly influenced by freeze–thaw-induced soil structural changes.

The incident involved sudden inrush of water and sand, leading to large-scale surface subsidence and municipal pipeline damage. A comprehensive analysis was conducted, including emergency response measures, post-incident geotechnical investigation, and numerical simulations. The incident response included emergency backfilling, pipeline reinforcement, and composite ground stabilization using Metro Jet System (MJS) and secant pile walls.

The macro-meso dynamic response of the ballasted track during uphill operation of the rack railway vehicle was revealed, offering theoretical insights for rack railway track design. The results indicated that when the gradient is below 400 ‰, both lateral and longitudinal resistances decrease approximately linearly with the increasing gradient.

Therefore, for rack railway lines with gradients greater than 400 ‰, it is crucial to carefully evaluate the mechanical performance of the ballasted track to ensure its stability.
