【Abstract】 Gushing water is the most common geologic hazard during tunneling. The data of hydrologic geology along the line of the tunnel are to be got as detail and precise as possible for its design and construction, when a long and deep embedded tunnel is to be excavated; for which the problems from gushing water can be dealt with the countermeasures of "prediction, prevention, drainage and sealing" in accordance with the actual construction phases and conditions. During tunneling, the quick, lower cost and intuitionistic prediction methods of fore-probing must be fully used for the sections in which the gushing water is possible to occur, so as to make a correct judgement in time. Furthothermore, for the sections in which the possibilities of the occurrence of the gushing water have been confirmed, the relevant fore-treatments have to be made in according to the actual conditions respectively , so as to avoid the hazard from the opening of the seepage path.更多还原
