| 摘 要： | 对于越过截渗墙的剖面二维含自由面的渗流,应用保角变换方法求解,通过引入速度矢端平面和应用Schwarz-Christoffel变换,推导出了物理平面Z(x,y)和复势平面ξ(Φ,Ψ)的映射关系式.主要的待求参数和积分常量有4个,提出了相应的联立求解关系式.算例表明所提出的求解方法是可行的.

| Abstract: | Two-dimensional seepage flow of free-surface over cutoff wall has been solved by conformal transformation method in this paper.By introducing the hodograph plane and utilizing Schwarz-Christoffel transform,the mapping relational formula between the physical plane Z(x,y) and complex potential plane ξ(Φ,Ψ)has been deduced.The main four parameters and integrated constants also have been obtained by joint-solution method.The solution example indicates that the solution method is feasible. |
