冰雪冻害边坡监控方案研究

Study on monitoring schemes for the slope under the influence of snow and frost

以张家口某隧道滑坡体的综合整治为工程背景,采用地下水位监测、坡表位移监测、深部位移监测等多种监测方法对坡体进行监测。研究结果表明,抗滑桩位移不明显,边坡整体位移小于10 mm,整个滑坡体的整体位移方向为西北方向,5号钻孔下部存在一个错动体,2号与5号孔间裂缝宽度增大约4 cm。此次研究可为类似边坡监测方案的制定和防治措施优化提供帮助。

In this paper,the monitoring of the slope is carried out using groundwater level monitoring,slope displacement monitoring,deep displacement monitoring and other monitoring methods in a Zhangjiakou tunnel. The results show that,anti-slide pile displacement is not obvious,and the slope overall displacement is less than 10 mm. The overall displacement direction of the whole landslide body is northwest. This study will help for the development of similar slope monitoring programs and optimization of control measures.
