G109国道门头沟区段沿线不良边坡的变形破坏特征及成因分析

Deformation Characteristics and Cause Analysis on the Unstable Slope along the National Road G109 in Mentougou Section

山区公路多具有边坡数量众多、地质条件复杂、地质灾害隐患发育且突发性强等特点,故由地质灾害所导致的危害和损失比较严重,由地质灾害隐患所构成的潜在威胁十分巨大。在门头沟区主干公路崩塌灾害隐患勘查工作基础上,对G109国道门头沟区段沿线的不良边坡的变形破坏特征进行初步研究,并对其成因进行分析与探讨。

There are a lot of slope along the mountain road,they have complicated geological conditions,become many potential disasters that may happen suddenly. It is likely to cause serious harm and loss,constitute a huge potential threat. On the basis of the potential collapse disasters exploration along the trunk road in Mentougou county area,the paper discusses the potential collapse disasters along the national road G109 Mentougou section,preliminarily studies the deformation characteristics of the unstable slope,analyses the causes of the unstable slope deformation.
