摘要
本文在论述岩溶塌陷探测现状的基础上提出了直接测氡法探测岩溶塌陷的地质机理，以唐山典型岩溶塌陷地段为研究点，证明了直接测氡法探测岩溶塌陷平面位置和分布的应用性，并给出用直接测氡样本判断岩溶塌陷存在与否的判别式和判断原则。
irstly, based on the survey current situation of karst collapse, this paper discussed the geologic mechanism of karst collapse surveyed by radon direct measurement method. Then taking the typical areas of karst collapse as a study spot in Tangshan, the applicability of plansite and distribution of karst collapse surveyed by radon direct measurement method are testifyed. Finally, according to the sample of radon direct measurement, it is proposed the differenttiation formula and judgement principle of karst collapse.
