复杂地质条件下高边坡加固设计与综合治理研究——以梅河高速公路某高边坡治理为例

梅河高速公路是广东省地质地理条件复杂的山区高速公路之一。其中K110 778~K110 960段左侧边坡在施工期间发生了三次滑坡,影响到了工程的建设与安全。介绍了该边坡的概况,从其形成条件和诱发因素两个方面较为系统的分析了该边坡的成因及其发展规律,通过选取代表性的断面,结合有限元分析技术对其加固前后的稳定性进行了分析,对该类边坡的治理方案进行了较系统的研究。研究对类似工程中的滑坡治理具有较好的借鉴意义。

Research on Reinforcement Design and Comprehensive Improvement for High Slopes Under Complicated Geological Conditions

MeiHe Expressway is one of the mountainous area expressways under complicated geological conditions in Guangdong Province,China.K100 778~K110 960 is a typical one with three times sliding in the period of rainfall seasons.The sliding of this landslide have strong affections for the construction and management of this expressway.A general introduction on the slope of K100 778~K110 960,then analyses the mechanism and developing regularities of this landslide from formation conditions and induced factors are given.According to taking a certain cross section as an example,the slope stability before and after reinforcement is compared with the FEM simulation,then the reinforcement method for this kind of landslide with complex conditions is discussed;and also presents a useful reference for the similar types of landslides in the major project is presented.
