【摘要】 隧道施工中经常会遇到各种地质灾害,超前地质预报在隧道施工中非常必要。而在贵州山区煤系地层中进行隧道施工的超前地质预报提出了很高的要求。在地质勘查的基础上,通过高密度电法、地质雷达法、SSP散射剖面法,对水塘隧道出口多处采空区进行了精准的预报,为类似工程问题的解决提供了参考。更多还原

【Abstract】 Geological disasters frequently happen during tunnel construction.Geological forecast in advance is of vital importance in tunnel construction.However,standards are extremely high in the geological forecast in advance in tunnel construction in coal measure strata of mountainous area in Guizhou province.On the basis of geological survey,by using high density electrical method,georadar method and SSP scatter section method,accurate forecasts are made on several goafs at the pond tunnel exits,thus providing references for solving similar engineering problems.更多还原
