STUDY ON GEOLOGIC PROSPECTING TECHNOLOGY WITH HSP SOUND WAVE REFLECTION THEORY

Drilling is a common geologic prospecting method, which is meticulous, intuitive and accurate. However it also has its limitations just like high cost, complicated operation and limited drill holes. So the drilling method can't inform completely the area geologic condition. For fast, easy to complete large multi-point test, authors apply sound reflection technology to geologic prospecting work of WANGJIA housing estate new relocation site in Sichuan ABA. In this paper, HSP sound wave reflection theory is introduced in detail, and geological foundation geological conditions can be speculated using time-domain and frequency domain analysis of geological changes, based on further investigation of geological structure. The results of contrast test verify that HSP sound wave reflection method used to launch geological survey is simple and feasible, fast and effective. This paper provides an example for similar projects in analysis and speculation of sound wave reflection method.
