武广高速铁路路堑边坡变形破坏特点与处治措施

Deformation Characteristic and Treatment Measure of Cutting Slope in Wuhan-Guangzhou High-speed Railway

武广高铁沿线分布有大量的软质岩和土质路堑边坡,由于强降雨及开挖后边坡加固与防护工程的滞后等原因,部分工点在施工期间产生了大小不一、因素复杂的变形破坏。从工程地质条件、水的作用和工程活动等方面,分析了边坡变形破坏产生的原因及影响因素;基于对处治措施的技术可行性、适用性、安全性及经济性等综合考虑,对部分典型工点的处治方案进行了介绍。处治工程取得了较好效果。

A large quantity of soft rock and soil slope are distributed along Wuhan-Guangzhou High-speed Railway.For strong rainfall and slopes not reinforced and protected timely after excavation,some construction points were deformed of different sizes with complicated factors during construction period.From the aspect of geological conditions,water action and engineering activities,the cause and influencing factors of slope deformation were analyzed in this paper.Based on considering the technical feasibility,applicability,safety and economical efficiency,the control measures of some typical construction points were introduced,which achieved better effect.
