摘要
通过收集西南山区5条铁路路堑高陡岩质边坡数据资料,利用粗糙集理论对影响边坡稳定性的众多因素进行约简,找出了最重要的一组因素。同时,计算出各因素在影响边坡稳定性中所占的权重值,为后续建立边坡稳定性评价体系提供重要的依据。
By collecting data of steep rock cutting slope along five railways in mountainous areas in the south- west, the factors affecting slope stability, by using rough set theory, were reduced so as to find a group of most important ones; simultaneously, the weight of each factor was calculated, which is the key basis to establish the system evaluating slope stability later.
