Anisotropic spatial variability of soil properties is frequently encountered in geotechnical engineering practice due to the complex depositional process. To quantitatively evaluate response slope failure related anisotropic and reveal underlying influence on reliability, this study integrates random finite difference method (RFDM) into a probabilistic assessment framework adopts general cohesive-frictional example for illustration. A parametric analysis carried out investigate probability...
Currently, the pile foundation underpinning technology is widely used when underground transportation infrastructure passes through existing buildings or structures in urban areas. This study aims to investigate stress transfer mechanisms foundations during an process as well influence of shield tunnel construction on stability. To this end, China's Shenzhen Metro Line 10 crossing bridge group Guangzhou–Shenzhen highway was analyzed detailed. The refined numerical simulation and processes...
Moraine soils are widely distributed in the Qinghai-Tibet Plateau. With increased global warming, moraine soil-related geohazards have become increasingly common, posing a serious threat to infrastructure (e.g., Sichuan–Tibet Railway) and inhabitants of this region. This paper aims investigate mechanical behavior ice-rich soil Tianmo Valley by conducting series triaxial constant strain rate (CSR) coupled thermomechanical (CTM) tests on artificially containing different ice forms (crushed...
The aim of this study is to develop a method simulate the behaviors clayey gravel during water erosion by using computational fluid dynamics–discrete element method. phase was solved "fixed coarse-grid" scheme based on Navier–Stokes equations, and solid described an assemblage discontinuous particles in Particle Flow Code three dimensions (PFC3D) modeling framework. A fictitious clay introduced, which suffosion matrix translated strength degradation bond according law. law embedded into...
The time-dependent hydromechanical behavior of rocks is crucial to assessing the long-term stability rock engineering, such as reservoir slopes and underground waste storage facilities. This research aims at developing a discrete-element method (DEM)-based numerical simulate whole water-induced carbonate failure process, which highly sensitive water with maximum 70% loss mechanical strength when saturated by water. First, degradation laws for induced were derived based on different behaviors...
Abstract This study investigated the degradation mechanism of surrounding rock a heavy-haul railway under water-rich condition, based on construction Taihangshan tunnel for Wari Railway, that used standard practices axle loads 30 t. Remote monitoring demonstrated coupling effect between dynamic load train and groundwater leads to deterioration hollowing rock. clarified void evolution process basement comprehensive influence groundwater–train using refined discrete element numerical...
In this study, an investigation on the formation mechanisms, deformation characteristics, and stability of Outang landslide, composed by three independent blocks (O1, O2, O3), is performed integrating site surveys, multi-technique monitoring data, numerical simulation. The results show that mechanism for O1 O3 slide-bulking, planar slide block O2. These along incompetent layers (ILs): IL1 slip surface IL3 O3. Furthermore, west local fast movement zone might evolve into deep failure. slope...
Abstract A warming environment is promoting the thawing process in ice‐rich moraine soils cold alpine regions, thereby accelerating formation/development of geohazards these regions. The mechanism closely related to thermal‐hydraulic (TH) coupling behavior soils, which has rarely been investigated. Here, we conducted a series bench‐scale TH simulations with ice inclusions environment. numerical model was conceptualized from field survey on Qinghai‐Tibet Plateau, consists porous medium...
