为了解决南阳一隧道YK37＋930底板下大型富水溶洞处治难题，通过超前地质预报、钻探和人工洞下查看等探测技术，采集了溶洞区域的地质资料，进行了溶洞形态描述。对溶洞区域内的水文、地貌、落水洞分布等情况进行了调查研究，依据收集到的资料提出了对隧道底板下富水溶洞采用地表落水洞封堵和洞内拱桥跨越相结合的处理方案，介绍了富水溶洞隧道洞内施工关键点。经过运营监测，证明溶洞的处理方案及施工方法都是正确的，可为今后类似工程提供借鉴。

The geological conditions of the huge water-rich karst cave under the floor at YK37 + 930 of a tunnel in Nan- yang is forecast by means of advance geology prediction, exploration drilling and labor investigation. The hydrology, ge- omorphology and sinkhole distribution are investigated. Countermeasures, including ground surface sinkhole blocking and arch bridge crossing, are proposed, on basis of the data collected by investigating and studying on the hydrology, topographic feature and sinkhole distribution. The key points of the treatment of the water-rich karst cave are presented. The operation and monitoring of the tunnel show that the treatment technologies for the karst cave are rational and effec- tive. The paper can provide reference for similar projects in the future.
