摘要
自由面包括潜水面和溢出面等。在地下水流分析中， 渗流自由面位置的确定至关重要。对于多孔连续介质渗流来说， 渗流自由面可用初流量法确定， 渗流自由面是一个连续的曲线；对于非连续的裂隙网络渗流来说，渗流自由面可用文中提出的迭代法进行，其渗流自由面是一个非连续的曲线， 即在裂隙处为潜水位， 在岩块处为承压水位。
The determination of free surface of seepage is very important in the analysis of groundwater flow. For continuous seepage in porous media, the free surface of seepage can be determined by initial flow rate method. The said surface is a continuous curve. For discontinuous seepage in the fracture network of rock mass, the free surface of seepage can be determined by iteration method which is proposed herein. The free surface of seepage is a discontinuous curve combined by the water table in the fracture and the confined hydraulic head in the solid matrix.
