【摘要】 本文依据岩溶区岩土体的物性差异,利用波阻抗和电阻率差异,对比分析了高密度电法、瞬变电磁法、地质雷达法等几种物探方法,最终确定了高密度电法、地震映像法及声波测井和钻孔CT法等地表和地下物探手段相结合的方法来探测岩溶分布与发育情况。更多还原

【Abstract】 This paper is based on the karst area of geotechnical engineering.It uses the difference in physical characteristic of the rack and soil and the wave impedance and resistivity differences.It comparatively analyses the high density resistivity method,the transient electromagnetic method,the geological radar method and other geophysical prospecting methods.Finally it determines the high-density electrical method,the seismic imaging method,the acoustic logging and drilling CT methods,as well as the surface and subsurface geophysical exploration methods to detect the site conditions of combining the karst distribution and the development conditions.更多还原
