| 摘 要： | 核磁共振找水仪(NMR)应用于滑坡地下水研究具有广泛的前景。本文以三峡工程库区巴东县赵树岭滑坡为例,说明利用NMR测试成果确定岩土层水文地质参数的方法,同时根据滑体含水量变化特征,进行滑坡的地下水含水层划分、滑动面确定,改进滑坡稳定性计算。利用NMR测试所测定的滑坡体地下水特征,进行赵树岭滑坡刚体极限平衡分析和有限元数值模拟,结果表明地下水特征对滑坡稳定影响很大,利用NMR可以更准确和有效地进行滑坡稳定性研究。

| Abstract: | NMR water exploration instrument is an effective equipment in the research of the groundwater in landslide. In this paper we take Zhaoshuling landslide as an example and introduce the method to determine hydrogeological parameters of rock and soil. Also we put forward a new way to divide sliding zone for the stability analysis of landslide. Through modified residual pushing method calculation and finite element simulation, we find that the stability of Zhaoshuling landslide is strongly influenced by groundwater and it is concluded that landslide stability can be more effectively studied by the method of NMR. |
