摘要
结合某隧道的工程概况,利用超前钻探技术,通过放水试验、水压观测等手段准确分析了隧道前方遇到的岩溶形态,准确判定岩溶水情况,从而选择有效的施工方法对其进行处理,保证施工安全。
Combining with the project survey of some tunnel, the paper analyzes the karst forms ahead of the tunnel construction and gives correct identification of the karst water by adopting the pre-detecting drilling technique and some measures, such as the dewatering tests and the inspection of water pressure, so as to select some effective construction measures, in order to guarantee the construction to be safe.
