Abstract Large rock avalanches are ubiquitous surface hazards on Earth and characterized by long runout distances high velocities. These extreme mobility features regarded as the key causes of catastrophic damage. Commonly, these a complicated set geological settings behaviors. Although many hypotheses have been proposed to explain this phenomenon, comprehensive explanation its is lacking. To precisely identify mechanisms large avalanches, we examined data collected from deposit Nyixoi...
There are a large number of high liquid limit soil distributed in southern China. As one the special soils commonly seen highway construction, cannot be used subgrade filling directly due to its engineering properties. With idea saving investment and protecting environment, must improved qualified material. First, detailed laboratory tests carried out reveal properties soil. Then, based on characters soil, improving plastic limit, unconfined compressive strength, CBR compaction completed by...
Understanding how landslide deposits form can help achieve a better understanding of the overall dynamics. Previous studies have focused on global characteristics runout process and final deposit, without attempting to comprehend deposition underlying mechanisms. Here, we employed combination flume experiments numerical simulations based material point method (MPM) investigate influence friction rock avalanche gain deeper mechanisms involved. MPM generally relied simple soil constitutive...
Leakage channels in the tunnel lining and surrounding rock can cause water seepage on walls, significantly impacting safety stability of operations. Therefore, precise detection leakage within is essential for maintaining safety. In this paper, based theory natural potential field exploration, distribution electric walls investigated. An improved particle swarm optimization algorithm applied to invert spatial charge rock. The charges used infer location direction rock, providing guidance...
Abstract The field investigation of the seasonal coarse grained frozen soil slopes along eastern section proposed Sichuan-Tibet railway shows that deformation and failure are widespread. In order to explore characteristics mechanisms in this area provide a basis for design protection railway, laboratory model tests on under snowfall conditions were conducted. results show that, slope caused by repeated alternation surface structure frost heave saturation snow thaw infiltration, reduction...
In order to investigate the influence of correlation scale error on inversion precision hydraulic conductivity aquifer, successive linear estimator (SLE) was used invert field a heterogeneous aquifer based synthetic experiments. By increasing numbers observation wells and pumping tests, we analyzed difference between estimated true values with different errors. The relationships well number in results, test results were investigated. show that, if amount observed head data is insufficient,...
Abstract The physical significance of the traditional slice block method analysis a slope is presented in this paper. strength-softening characteristics geomaterial are characterized by strength reduction coefficient post-failure zone stress–strain curve complete process. In study, transfer (TCM) hypothesis was generalized, and partial (PSRM) perfect elastoplastic model (PEPM) were employed. progressive failure process simulated proposed generalized method; critical-stress-state...
