摘要
目前,在国内外岩溶超前地质预报手段中,隧道地震波法(TSP)及地质雷达法(GPR)为针对岩溶问题的主流地质预报手段。两种预报手段在岩溶超前地质预报中各自具有其优点和缺点,但单一采取其中一种方法在岩溶预报中存在诸多问题。以此为背景,结合依托工程龙厦铁路象山隧道,将"TSP+GPR"综合预报模式应用于龙厦铁路象山隧道岩溶段,并通过与开挖情况对比和研究,说明"TSP+GPR"预报模式在岩溶段地质超前预报的整体效果。
TSP and GPR methods are the main geological forecast methods for karst advance geological forecast. Each of them has its advantages and disadvantages. In this paper, " TSP + GPR" comprehensive forecast model was applied in XiangShan tunnel of Longxia railway construction. The overall effect of this model in karst geological advanced forecast was studied.
