【Abstract】 The paper introduces several underground rivers encountered in the excavation of Wulong tunnel, summarizes the features of them and describes the general idea about the water outbursts from underground rivers. The emphasis of tackling the underground rivers in tunnels is on the design and construction of the system of waterproofing and drainage. The comprehensive disposal follows a series of principles that regards drainage as the main measure, with stopping and cutting water in coordination, together with the maintenance of the system of waterproofing. Several ideas and proposals are put forward when underground rivers are encountered in tunneling that may be served as a guidance for similar projects.更多还原
