西气东输管道吕家河滑坡与应急治理

Lvjiahe Landslide in West-to-East Gas Transmission Pipeline and Emergency Measures

对于西气东输管道山西吕家河滑坡的地貌条件、构造条件、发育特征、诱发因素进行了初步分析与研究,从地质学的角度指出滑坡产生的根本原因是其后缘受煤矿场区施工、弃渣及其挡墙的加载影响,坡体前缘芦苇河河流冲刷则是另一诱发因素。根据研究结果,制定了改善滑坡段环境、管道改线和加强管道巡查等应急措施。

Initial study and analysis on Lvjiahe landslide in West-to-East Gas Transmission Pipeline of Shanxi Province are carried out from physiognomy,structure,development feature and inducing factors.Based on the geology,it indicates that one of the essential reasons of the landslide is a load-on effect of construction,waste residues and remaining wall of a coal mine on its after-edge;and the other is fluvial denudation of Luweihe River at its leading edge.Based on research results,emergency measures for the landslide including improving the environment around Lvjiahe landslide area,changing the route of pipeline and enhancing pipeline patrol are worked out.
