海西高速公路网南平联络线K26+300~+600段,存在由于多种原因形成滑坡,该滑坡的稳定性如何,是否对公路网的建设运行带来安全隐患,成为公路段建设期必须解决的工程问题。通过对滑坡的地质条件、形成机制及稳定性分析,发现该滑坡存在安全隐患,需要进行针对性治理。因此,采用削坡减载、三角形钢架桩、反压互道和坡脚挡墙为主,辅以外封地表水、深排地下水相结合的措施进行综合治理,监控量测数据表明采用综合处治方案治理该滑坡是行之有效的。
Haixi highway network Nanping contact line K26 +300 ~ +600 section, there are a variety of reasons for the formation of landslides, the stability of the landslide, whether the road network construction and operation of the security risks, become a highway construction period must be addressed Engineering problems. By analyzing the geological conditions, formation mechanism and stability of the landslide, it is found that the landslide has potential safety problems and needs to be treated in a targeted manner. Therefore, the use of cutting ramp load, triangular steel frame piles, back pressure each channel and the slope of the foot of the wall, combined with the outer surface water, deep groundwater combined measures to conduct a comprehensive management, monitoring data show that the use of comprehensive treatment The solution to the landslide is working.
