Application of Seismic Imaging Method in Detecting the Complex Geological Hazards
In recent years, geological hazards happened frequently, for example goaf, karst, ground fissure, landslide threatening engineering construction and human life severely. How to take some measures effectively and find out the space character of geological hazards are very important to control geological hazards. In this paper, we firstly explain the principle of seismic imaging method. Then analyze the character of geophysical abnormity in the different geological hazards, and discuss the effect of seismic imaging method in detecting the geological hazards. Meanwhile combining with some engineering examples, we have detected these geological hazards accurately and we can get some proofs from the borehole. It indicates that this method has lots of advantages in detecting geological hazards. For example high resolution, low cost, high efficiency and it can make up for disadvantages of other detecting methods.
