| Landslide is one kinds of geological hazard which is most commonly to seein mountainous area highway. Through the works of field investigation and studies based onthe high fill landslide of NO.316national road, LiangDang GaoZuZi, this article analyzed themain infulence factors which are led to form landslide, formation mechanism andclassification of landslide. And also proposed three feasible programs of landslide treatment,then did the qualitative analysis and quantitative analysis of rationality, safety and economicalfor each programs. Then proposed a comprehensive approach of landslide treatment, which ismainly based on reinforced concrete pile plate retaining wall, and combining with unload andimproved surface drainage.Based on the study of field investigation and reaserch of the geological references, thisarticle also did a feasible treatment engineering design for the collapsed original road, andalso did the structural calculation for reinforced concrete pile plate retaining wall. Accordingto the factors of this project, this article proposed a rebulid program for the culvert disruptedby landslide, which using Steel corrugated pipe culvert, as well as the treatment design forpavement structure, building materials, construction requirements and also maintaining trafficmoving.According to the analyze of the results of this project, it can be see that using reinforcedconcrete pile plate retaining wall is a effective approch for landslide treatment in mountainousarea, especially for the shoulder retaining wall with high filled side slope and limited terrain,and disaster treatment for landslide of high filled side slope. The result of this project provedthat this treatment engineering design in this article is successful, and it also provide areference for landsilde treatment in damp area of mountainous places and collapse of highslope. |
