%X 岩溶是工程建筑项目中经常遇到的一种较为典型的地质灾害，会给工程建筑的安全带来巨大的隐患。为了找出建筑地基中岩溶的分布及发育情况，要多次进行地下岩溶勘探。由于场地条件的原因，传统的地球物理方法基本无法正常开展工作。因此根据岩溶与围岩的电性差异特征，运用瞬变电磁法(TEM)对建筑场地岩溶发育区进行探测。实践证明，采用瞬态电磁法对查明施工现场岩溶的分布范围、规模大小和埋藏深度有良好的效果，可为进一步的调查工作提供重要的参考价值及指导性意义。<br />
Karst is a typical geological hazard often encountered in engineering construction projects, it will bring huge hidden dangers to the safety of engineering buildings. In order to find the distribution and development of karst in the building foundation, it is necessary to conduct multiple underground karst exploration. Due to the site conditions, the traditional geophysical methods can not work normally. Therefore, according to the electrical characteristics of karst and surrounding rock, use transient electromagnetic method (TEM) to detect the karst development area in the construction site. Practice has proved that the use of transient electromagnetic method has a good effect on finding out the distribution range, scale and buried depth of karst at the construction site, which can provide important reference value and guiding significance for further investigation.
