K剖面法在黄腊石滑坡勘察中的应用研究

介绍了K剖面法在黄腊石滑坡中的应用情况。K剖面法全称“反射系数法电法勘探”,简称“K剖面法”,是长江水利委员会孙经荣于20世纪70年代末正式提出的一种地球物理勘探解释方法。黄腊石滑坡,位于三峡水库区巴东县城以东2km处的长江北岸,距三峡大坝坝址66km。由于规模较大,且距三峡坝址较近,又有复活现象,因此,被列为三峡库区近坝库段三大不稳定滑坡之一。实践表明K剖面法尤其对崩坡积滑坡的勘探有效,而且可以获得较完整的、宏观的有关滑坡地质结构的物性资料,这一点其它勘探方法是不可能具有的。

K Section Method and Its Use on Huanglashi Landslide

The application of K section method in Huanglashi landslide is mainly introduced in this paper.The full name of K section method is reflectance electricity method reconnoiter.It is one of physical geography reconnoiter method,which was brought forward formally by Sun Jingrong by the end of 1970s,who is in the Yangtze River Water Conservancy Council.Huanglashi landslide which lies in north bank of Yangtse River,that is,from Badong county 2 kilometers eastwardly,which is in The Three Gorges Reservoir.Due to a large scale,small distance from The Three Gorges dam site and revival Huanglashi landslide is one of the three insecure landslides near the dam.We can conclude that K section method is effective in exploring collapse landslide and especially we can get the integrated and macroscopic information about geological structure of landslide.Other reconnoiter methods cannot do like this.
