山西省高速公路滑坡初探

山西省地质条件较差,在修建高速公路的过程中经常发生滑坡灾害,成为高速公路建设的瓶颈和关键技术问题。通过对山西省已建8条高速公路沿线75处滑坡的归纳总结,根据滑动面及滑体物质的不同将滑坡分为切层、顺层、破碎岩石滑坡及黄土、粘土、堆积土滑坡。并从地层岩性、地质构造、新构造运动、降雨及人类工程活动五个方面,对其规律性进行了研究分析,得出了山西省高速公路滑坡的突出特点,可为以后山西省高速公路的规划建设提供借鉴参考。

Preliminary analysis of landslides in Shanxi express highway

The geological condition is poor in Shanxi province.During construction of express highway,landslides usually appear,and this problem has been bottle neck.According to generalization for 75 landslides of 8 express highways in Shanxi province,landslides were divided different types,that is,bedding landslide,fragmenting rock landslide,loess landslide,clay landslide and cumulose landslide.From stratum,geological structure,neotectonic movement,rainfall and human engineering,study regularity,and generalize main characteristics of express highway in Shanxi province.The conclusions can provide reference to planning and construction of express highway in Shanxi province in future.
