摘　　要：结合山西省万家寨引黄一期工程南干6#隧洞工程实例,介绍了6#隧洞围岩岩溶的发育特征。隧洞围岩为碳酸盐岩,通过前期勘察基本查明了工程区岩溶发育特征、类型、岩溶发育程度,表明南干6#隧洞是该工程岩溶最为发育的洞段。TBM施工证明了这一结论。而后通过地质雷达探测和洞内钻探取样试验,也进一步佐证了这一结论,并为岩溶处理工作提供了依据。Based on the actual case of the Tunnel No.6 for the South Main Route of the Phase Ⅰ of Wanjiazhai Yellow River Diversion Project in Shanxi Province,the characteristics of the karst development of the surrounding rock in the tunnel No.6 is described herein.The surrounding rock is a kind of carbonate rock,for which the characteristics,types and degree of the karst development are basically determined during the prophase investigation concerned.It shows that the tunnel is the most developed karst section within the whole diversion project,which is proved by the TBM construction made therein.After that this conclusion is also proved by the detections made by both the geological radar and drilling,and then a better basis is provide for the treatment on the karst.
