公路隧道通过岩溶发育区的综合地质超前预报体系探讨

Discussion on Comprehensive Geological Advance Forecast System of Highway Tunnel through Karst Area

目前,国内越来越多的隧道会穿过灰岩溶蚀区,这些区域会对隧道的安全掘进造成一定的影响。对此类隧道施工常用的物探手段进行了探讨,对一些工程实例进行了深入分析,总结了隧道通过灰岩溶蚀区有效的地质预报手段,并对各预报手段形成的隧道地质预报综合体系进行了初步探讨。

At present, more and more domestic tunnel passes through the limestone dissolution area, these areas may affect the safety of tunnel excavation. To this kind of tunnel construction geophysical methods commonly used are discussed, some engineering examples are analyzed deeply, summed up the tunnel geological prediction by means of limestone dissolution zone effective, comprehensive tunnel geological forecast system and the formation of the prediction methods were discussed.
