为实现悬挂式帷幕条件下涌水量定量计算以及基于此的优化设计，根据地下水动力学原理，分析了悬挂式帷幕影响下形成的绕流和非绕流两个区的渗流特征；利用Dupuit假设和阻隔理论，在一定理论推导基础上，系统地提出了悬挂式帷幕条件下潜水和承压水涌水量计算的修正大井法，并根据实际应用需要提出了相应的近似表达式；然后，以潜水含水层为例，采用系统的数值试验分析了修正大井法中水位加权系数随悬挂式帷幕深度变化规律，同时也验证了修正大井法近似公式精度；最后对悬挂式帷幕优化设计进行了探讨，提出了优化模型和求解方法，并进行了相关数值案例的应用。

In order to calculate flow rate under suspended curtain, in which the design of suspended curtain can be optimized, based on the principle of groundwater dynamics, the characteristics of flowing-around zone and non-flowing-around zone formed under the influence of suspended curtain was analyzed respectively; With Dupuit hypothesis and damming effect theory, on some theoretical derivation, the modified large-well-method ( MLWM) to calculate discharge rate under the suspended curtain for phreatic and confined water was introduced systematically, considering the needs of practical application, whose approximation( AMLWM) was deduced. Then, in the case of phreatic aquifer,by systematical numerical tests, the law of weight coefficient of water level ( WCWL) in MLWM versus suspended curtain depth into stratum was studied, and the accuracy of AMLWM was verified. At last, the optimum design of the suspended curtain was discussed, in which the optimum model and its solution was introduced, which was applied to some relative numerical case.
