山区修建铁路,由于地形地质条件比较复杂,经常出现滑坡,给铁路正常施工带来很大困难。解放以来,铁路建设中整治滑坡的工程措施不断在发展,大致可分为三个阶段:建国初期,限于施工水平,主要靠清方减载。每遇滑坡,都要做大量土石方,有时甚至把整个滑坡体清掉。这不仅多用劳力,拖长工期,加大工程成本,有时还破坏 Because of the complicated topographic and geological conditions, landslides often occur in mountainous areas to build railways, which brings great difficulties to normal railway construction. Since the liberation, the engineering measures for controlling landslides in the railway construction are under continuous development. They can be roughly divided into three stages: in the early days of the founding of the People’s Republic of China, the construction was limited mainly by the reduction of load by the Qing Fang. Whenever landslides, have to do a lot of earth and stone, and sometimes even the entire landslide cleared. This not only increases labor costs, prolongs the construction period, increases the cost of the project, and sometimes destroys it
