| 摘 要： | 地下水长期作用于灰岩裂隙往往使岩溶或破碎带更加发育,形成地下溶洞,给工程建筑安全带来极大的隐患和危险。为了查明建筑基地岩溶分布及发育情况,根据岩溶与其周围介质的电性差异,综合运用高密度电阻率法和瞬变电磁法,探测武汉市江夏区一新建小区场地的地下地质结构。实践表明,综合物探方法的应用,其探测效果可以起到互相验证及互相补充的作用,可为建筑工程提供不同深度可靠的、精确的地下地质基础资料。

| Abstract: | The underground cavity and karst caused by long-term effects of groundwater in carbonate area can bring about hidden danger and disaster for engineering construction.In order to investigate the distribution and development of the karst situation in construction site,according to their electric difference of the target and around matter,high-density resistivity method and transient electromagnetic method（TEM）were used to investigate the underground geological structure in a block of Jiangxia district,Wuhan city.It proves that the application of integrated geophysical techniques can play an important role of mutual verification and mutual complement,which can give the reliable,accurate subsurface geological information at various depth for the construction engineering. |
