Zusammenfassung |
Landslide is a major
disaster resulting in considerable loss of human lives and property damages
in hilly terrain in Hong Kong, China and many other countries. The factor of
safety and the critical slip surface for slope stabilization are the main
considerations for slope stability analysis in the past, while the detailed
post-failure conditions of the slopes have not been considered in sufficient
detail. There is however increasing interest in the consequences after the
initiation of failure that includes the development and propagation of the
failure surfaces, the amount of failed mass and runoff and the affected
region. To assess the development of slope failure in more detail and to
consider the potential danger of slopes after failure has initiated, the
slope stability problem under external surcharge is analyzed by the distinct
element method (DEM) and a laboratory model test in the present research. A
more refined study about the development of failure, microcosmic failure
mechanisms and the post-failure mechanisms of slopes will be carried out. The
numerical modeling method and the various findings from the present work can
provide an alternate method of analysis of slope failure, which can give
additional information not available from the classical methods of analysis. |
