The stability of large-section clay tunnels is closely related to the mechanical behavior surrounding rock. rock characterized by coupled response physico-mechanical properties material and tunnel construction conditions. Therefore, this paper proposes a numerical experimental study based on surface method quantitatively link with factors. It will provide basis for guiding plan adjustment ensur...

Retrogressive landslide is caused by the lower rock mass sliding, so that upper part loses support, deformed, and starts to slide. In process of highway construction, incised slope often leads retrogressive landslide, determination damage range great significance for control slope. Taking a in Hunan Province as research object, particle flow discrete element used numerically simulate entire fai...

The stability of the rock mass is generally constituted by presence and behavior discontinuities. flow water in a one parameters that considerably affect fractured behavior, strength, stability. This study proposes triaxial compression test to determine stress, strain, failure modes penetrating under static load, reveal relationship between its deformation strain rate, fracture slope, water. AB...

by Craig Abram Jordan, M.S. Washington State University Chair: Balasingam Muhunthan Landslides constitute a major geological hazard in the world due to their high financial cost and their nondiscriminatory nature. The Olympic Region of Washington State has many potential triggers of landslides, but prolonged periods of high rainfall is the most commonly attributed trigger of landslides. The cur...

Slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. In slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. Therefore, accurate reproduction of the spatial variability in ...

In order to reduce the risk of slope stability evaluation due fuzziness calculation parameters, a finite element analysis method based on fuzzy statistics is proposed. Based principle quasi-static and with help software COMSOL multiphysics, this paper studies gravel soil accumulation rock under action different seismic acceleration. By analyzing displacement, plastic zone safety factor slope, a...
