Seismic Refraction Method to Determine the Fundamental Rock Depth for the Wanjiazhai Key Water Control Project

在万家寨水利枢纽右岸的辅助工区,由于地质条件特殊,地震折射波法所获资料用常规方法无法解释,而采用“递推法”解释效果好。本文阐述了应用“递推法”需注意的问题,并用波路计算提高了资料解释的精度。

In the determination of the depth of fundamental rocks for the key water control project,seismic refraction method was used.The data obtained are unable to be interpretated by conventional methods due to the special geological condition of the study areaencountered.For this reason the recurrence method was used for data interpretation and the accuracy of the interpretation wasraised up by checking with wave path calculation.Through these effective measures undertaken,good results were obtained.In ad-dition some problems that should be noted upon the recurrence method and wave path calculation are discussed in this paper.
