山区高速公路差异风化边坡工程滑坡治理研究

山区高速公路建设过程中,高填深挖路段难以避免,因边坡开挖扰动山体造成坡体应力集中释放,从而引发滑坡、坍塌等不良工程地质灾害的情况时有发生。以云南省保山至腾冲高速公路K8+920~K9+160段高边坡工程滑坡治理为例,结合现场勘察和试验资料,以数理建模完成滑坡稳定性分析,提出针对岩性相同但差异风化明显的工程滑坡的综合治理方案。体现了山区高速公路修建过程中,对于此类工程滑坡,结合实际地质条件和数理分析,合理选择治理措施的重要性,并为同类型滑坡治理工程提供参考。

Research on Differential Weathering Engineering Landslide of Freeway in Mountainous Areas

It is difficult to avoid the high filling and excavation section in process of freeway construction in mountainous areas. It is because of the slope of mountain digging disturbance that makes the stress concentration release, then causing landslides, collapse and other engineering geological disasters. Take the treatment of high slope landslide at K8＋920-K9＋160 in the freeway from Baoshan to Tengchong in Yunnan Province as an example, stability analysis of landslide have done by modeling combined the field investigation and experimental data, and put forward comprehensive control scheme for the same lithology but different weathering obvious engineering landslides. Showing the necessity of that when we put forward the treatment of this kind of engineering landslide analysis in highway construction process, we have to consider the actual geological conditions and reasonable selection of mathematical. And providing reference for engineering treatment for the same type of landslide.
