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.
