Mechanism of Horizontal Layered Soil Slope Failure
摘要
Abstract
For horizontal layered soil slope into a layer characteristics, establishes model tests to simulate the bearing characteristics and failure mechanism. By means of the mutual verification analysis of FLAC3D numerical simulation and indoor model tests, gets load - displacement law, ultimate bearing capacity and the sliding surface shape and position under the top loading of layered slope. The results show that the ultimate bearing capacity increases with the layer thickness increment, and the influence of slope height to the ultimate bearing capacity is minimal. Applies FLAC3Dfor expand analysis and uses the contact of failure mechanism between layered slope and homogeneous slope to obtain the relationship between layered slope cut height with load width and slope ratio, meanwhile obtains the critical slope ratio in different failure modes. The results have certain reference significance to the actual project.关键词
