Detection of Subsurface Objects Using Special-Analysis-of- Surface-Waves

本研究的主要目的是探讨将地表波谱分析（SASW）方法与地质层析成像概念相结合，用于地下洞室探测和圈定的可行性，从而实现地下特征的三维制图。地下空洞和物体的存在会给结构、岩土和环境工程师带来严重的挑战，并可能危及公共安全。因此，需要找到方法来定位这些特征，作为可疑区域现场调查计划的一部分。经过改进的SASW方法将提供这样一种手段。

The main objective of this research is to explore the feasibility of coupling the Spectral-Analysis-of-Surface-Waves (SASW) method for the detection and delineation of underground cavities with the concept of geotomography, so that a three-dimensional mapping of subsurface features can be accomplished. The presence of subsurface voids and objects can cause serious challenges for structural, geotechnical, and environmental engineers, and can jeopardize public safety. Therefore, methods are needed to locate such features as part of the site investigation program in suspect areas. SASW method with the proposed enhancement will provide such a means.
