摘　　要：分析当前普遍使用的“折减系数法”确定隧道外水压力中存在的问题 ,建议采用地下水流数值模拟法 ,并提出建模中的注意事项 。When determining the tunnel external water pressure, many disadvantages might exist in the generally-used method of reduction factor. In this paper, a proposed numerical model of groundwater flow is presented to acquire the tunnel external water pressure; furthermore, key points on model establishing including how to determine the boundary conditions are expanded accordingly.
