滑坡是黄土山区公路的主要病害之一。公路边坡或山坡发生滑坡,轻者导致掩埋家田,严重者毁坏建筑物,堵塞、摧毁公路,严重影响了高速公路的建设和运营。因此,黄土山区的滑坡病害的研究和防治是公路工程技术人员不得不面对的问题。文章根据在建的岢临高速公路K74+100～K74+500段王家嫣1号滑坡的实际情况,对黄土地区公路滑坡进行了稳定性计算与分析,并提出了相应的黄土滑坡的防治方案。
Landslide is one of the major diseases of highway in loess mountainous area. Landslides occur on the side slopes or slopes of the roads. Light ones lead to the burial of farm fields. In serious cases, they destroy buildings, block and destroy roads, seriously affecting the construction and operation of expressways. Therefore, the research and prevention of the landslide diseases in the loess mountainous areas are the problems which the highway engineering technicians have to face. Based on the actual situation of the Wangjiayan No.1 landslide on the K74 + 100 ~ K74 + 500 section of Yinglin Expressway under construction, the stability of the landslide in the loess area is calculated and analyzed, and the corresponding loess landslide prevention and control plan is put forward.
