摘要
滑坡裂缝是判定滑坡规模、分析滑坡形成机制、预测滑坡发展趋势、指导滑坡监测、治理的重要依据。分析了探地雷达技术进行滑坡裂缝特征调查的原理,确立了探地雷达进行滑坡裂缝调查的一般模式,并以四川华蓥市赵子秀山滑坡变形体的探地雷达探测为例,应用探地雷达技术获取了清晰反映裂缝位置、走向、深度的高质量图像。研究表明采用探地雷达进行滑坡裂缝探测是一种便捷有效的方法。
Landslide fissure is the evidence to define the size of landslide, analyze the formation mechanic character of landslide, forecast the development tendency of landslide, direct the inspection and control of landslide. Ground penetrating radar （GPR） is a new kind of shallow subsurface geophysical exploration instrument, it can be used under kinds of bad fieldwork conditions. This thesis analyses the principles, establishes the general mode of Landslide fissure survey of GPR, takes the exploration of Mt. Zhaozixiu, Huaying, Sichuan province for example, acquires high quality image which can show the location, direction and depth of the fissure clearly. The research shows that using GPR in landslide fissure survey is expedient and effective.
