DK163滑坡治理方案的回顾与反思

神朔铁路ＤＫ１６３＋７５０，在黄土阶坡上填筑的双线路基，沿线路长７５ｍ的路提产生了推动式工程滑坡变形，设计了抗滑挡工程。由于场地狭窄，通讯、电力线路拆迁协调困难，最终采取了清方设旱桥通过滑坡中后部的方案。大桥通车后，右侧刷方坡脚又产生了牵引式工程坡变形，增设了抗滑桩工程。本文介绍了该滑坡的发生及治理全过程。

SELECTION OF TYPES AND METHODS FORTHE RESTRAINT WORKS OF LANDSLIDE AT DK163

The DK163landslide located at the front flange of loess terrace in the Shenmu-Shuozhou Railway.Itoccured in double track embankment with an overall length more than 75 metres.Theanti-sliding retaining wall works were designed.Due to narrow of the site of constructionand difficulty of coordination for removal of the communication lines and the powertransmission line,finally,we take on removal landslide soil and builting viaductmeasure.After the viaduct of railway was open to traffic,the towed engineering landsildeoccured at the hillside of the soil removal works,and we take on restraint measure oflarge diameter cast-in-pile works.The paper presents mainly the geological condition,slidemechanism and restraint works.
