摘　　要：物探是查明滑坡体岩性及判别滑坡体结构、滑带空间分布的有效而快捷的手段之一。其经济成本低、覆盖范围不受地形条件限制,在勘察工作中已成为配合地质勘探工作的首选方法。本文结合一个工程实例,介绍三极电测深法用于高速公路滑坡勘探的基本原理、野外使用方法、滑坡的地球物理特性、滑坡的电测深曲线特征、资料解释及钻孔验证情况,证明电测深在高速公路滑坡勘探中的有效性,对此类滑坡的电探工作提出某些见解。Geophysical survey is a valid and fast method for landslide investigation about lithologic character and structure of gliding mass and spatial distribution of gliding plane. It has become the preferred method to cooperate with geologic investigation because of its lower cost and its overlay scope to be free from geography condition. This paper gives an example and introduces the using of tri-electrodes sounding method for landslide survey of high speedway. The essential principal, the field method, the geophysical character of landslide, the character of electrical sounding curve, the explain of data and the contrast condition with drilling record are introduced. The efficiency of the method is verified. Some ideas of geophysical survey for this kind of landslide are put forward.
