一种应用于三峡滑坡探测的新方法—SNMR法(英文)

A New Method of Detecting Landslides: A Case for SNMR

三峡库区蓄水后,由于水位上升滑坡地区的软弱层遇到水就会变软并引起滑塌。核磁共振是当今世界尖端技术之一,我们首先将该技术应用于滑坡探查。本文探讨了用SNMR探查滑坡的方法技术以及通过SNMR实测数据求取与滑坡稳定性有关的水文地质参数,通过一个三峡的实例说明了该方法是一种快速有效的探测滑坡的方法。

After the Three Gorges Reservoir impounded, due to the rise of ground water, the flabbiness layers in landslides will become soft and collapse when they meet water. During the running of the reservoir, the change of water level will bring huge dynamic water pressur~ which leads to slides, especially when the water level approaches sliding surface. It is a brandnew ideal research on ground water change characteristics and stability of landslides to use SNMR （surface nuclear magnetic resonance） . Except that a few papers have been published in our research group, there is no other reports or papers in or out of China. We take Zhaoshuling landslides in TheThree Gorges Reservoir as an example to study ground water characteristics and stability of the landslides Applying SNMR to research on landslides is a new method, and its success will not only pioneer a new way to study landslides and expand the application of NMR, but also promote the economic construction of our country. Therefore, it has both scientific significance and greatpracticality.
