摘　　要：山区岩溶场地地质条件复杂,如何准确查明地下岩溶的发育规模、形态、边界、填充情况并采取科学有效的处理措施是岩土工程界的一大技术难题。该文对山区复杂岩溶场地地下岩溶的勘察、处理关键技术进行了探讨,总结出一套适用于山区岩溶机场地下溶洞勘察与处理的综合技术手段,可提高地下岩溶勘察处理效益和精度,避免地面沉降、塌陷,保障工程安全。并在某岩溶山区机场工程中进行了应用,取得了良好的实际效果。The geological condition of mountain karst venues is complicated, how to accurately identify the development scale, shape, border, padding situation of underground karst and to take effective and scientific measures are a major technical problem for geotechnical engineering. In this article, the key technologies for surveying and processing underground karst in complex karst site in mountainous are dis- cussed. The comprehensive technical means which are suitable for underground caverns investigation and treatment in karst airport in mountainous area are summed up. It can improve the efficiency and accuracy of underground karst investigation and processing, avoid the ground subsidence ,collapse, and ensure engineering safety. And it has been applied in a karst airport project in mountain, and it achieves good practical results.
