兰临高速公路西果园滑坡复活变形因素分析

Analysis of Revivifying and Deforming Factors on Xiguoyuan Landslide,Lan-Lin Expressway

兰临高速公路K10+340～660段的西果园滑坡是古滑坡的复活,对西果园特大桥的施工与营运造成很大威胁。文章在研究滑坡形态特征、工程地质特征和变形特征的基础上,从水文地质因素、人类工程活动因素和大气降水因素等几个方面分析了诱发滑坡复活变形的主要原因。

Xiguoyuan landslide is a resurgent paleolandslide in Lan-Lin Highway K10+340～660 segment,construction and operation of Xiguoyuan super-huge bridge will be imperiled awfully by the landslide.Based on the study of the landslide configuration,engineering geology and deform features,the analyses main causes bringing out the landslide revivifying and deforming from geohydrology,human engineering activity and meteoric water factors.
