| Abstract: | Engineering Vertical Seismic Profile（EVSP） is that applicating VSP in the exploration of oil and gas into engineering, can directly and especially extract the in-situ dynamic elastic modulus of the rock features, which really and extractlly reflects the various by four-component surveying,two-wavelet monitoring and complex wave field analysing in the work of EVSP in drill hole No.1 in Baiyanjian in the Dam Area of the Three-Gorge Project of the Yangtze River,and interpretated the weathered zones,fractured zones,vein rocks in the granite mass around the hole.The continous elastodynamic module obtained are valurable for the engineering.Design and construction of the Three-Gorge Project. |
