张家界地区不稳定斜坡及滑坡对黔张常铁路选线的影响研究

通过对黔张常铁路张家界地区不稳定斜坡及滑坡的调查和分析,得出本区不稳定斜坡及滑坡的分布特点、成因机理及最主要影响因素。对边坡进行定性稳定性分析,并选取典型剖面进行了定量分析,同时初步评价不稳定斜坡及滑坡对工程建设的影响,进一步提出在该类地区选线时应注意的问题及选线原则,为线路的优化和滑坡防治提供了坚实的理论基础,同时希望提高对不稳定斜坡的认识和理解,引起对不稳定斜坡的重视。

Influence of Zhangjiajie Area Unstable Slope and Landslide on Qianzhangchang Railway Route Selection

Through researching and analyzing of the unstable slope and landslide of zhangjiajie area along Qianzhangchang railway,this paper summarizes the distribution characteristics of the unstable slope and landslide,the formation mechanism and the main influencing factors. A stability analysis of the side slope,and a quantitative analysis of selected a typical profile are carried out. Meanwhile preliminary evaluation of the influence of the unstable slope and landside on engineering construction is conducted.Furthermore,forwarded are issues to be addressed and route selection principle observed. These have provided a solid theoretical foundation for the railway optimization and landslide prevention. At the same time,it is hoped that recognizing and understanding of the unstable lope will be consolidated and great attention drawn to it.
