Karst soil cave exploring and positioning method
The invention relates to the field of karst region soil cave collapse geological disasters, in particular to a karst soil cave exploring and positioning method. The method comprises the following steps that firstly, a working area required to be subjected to collapse exploring is selected; a spraying route is delimited for the selected area, and foaming agents are evenly sprayed till the content of the foaming agents in the earth surface covering layer soil body reaches the designed concentration; then whether bubbles are continuously generated on the earth surface or not are observed after raining, bubble generation points are marked, namely possible development positions of the karst soil cave, and finally the bubble generation points and adjacent areas are detected in detail by adoptinga conventional drilling or geophysical prospecting method to determine detailed characteristics of the soil cave. According to the technical scheme, the karst soil cave exploring and positioning method can achieve large-area, low-cost, easy-to-operate and accurate detection of the specific development position of the underground karst soil cave, can remarkably reduce the detection target area ofthe karst soil cave, and effectively solves the bottleneck problem of restricting the position of the soil cave in karst collapse monitoring and prevention at present.
本发明涉及岩溶喀斯特地区土洞塌陷地质灾害领域，具体涉及一种岩溶土洞探寻定位方法，包括以下步骤，先选定需要开展塌陷探寻的工作区；再对选定区域划定喷洒路线并均匀喷洒起泡剂，直至地表覆盖层土体内起泡剂含量达到设计浓度；然后在雨后观察地表是否有气泡持续产生，并标记气泡产生点位，气泡产生点位即岩溶土洞可能的发育位置，最后采用常规钻探或物探方法，对产生气泡点位及临近区域进行详细探测，确定土洞的详细特征；采用本发明技术方案的岩溶土洞探寻定位方法，可实现大面积、低成本、易操作且较准确地探测地下岩溶土洞的具体发育位置，能显著缩小岩溶土洞探测靶区，有效解决目前制约岩溶塌陷监测和防治中“土洞在哪里”的瓶颈问题。
