| 摘 要： | 梯级开发水电站渣场设置的合理性是水土保持方案关注的重点.设置在河道两侧的渣场会束窄河道,对河道行洪等一系列问题产生影响.针对渣场设置是否会对河道行洪产生影响的问题,提出了河道水流的数值模拟计算方法.利用MIKE 21水动力模块对河道水流进行二维模拟,得到修建渣场前后河道水位及流场的变化.该方法的运用解决了编制水保方案时缺乏水文资料的水力计算问题,实现了计算的便捷化和合理化；同时还为渣场水土保持工程措施的设计提供了有力的依据.

| Abstract: | Spoil dump is an important problem in soil and water conservation schemes for hydropower cascadedevelopment.Improper setting of spoil dumps can easily narrow the river channel and influence river flooddischarge.Aiming at this question,a new calculating method based on numerical simulation of river flow wasproposed.Using the hydrodynamics module in MIKE 21model,changes of water level and flow field wereobtained by two-dimensional simulation before and after the existence of spoil dumps.This method solvedthe hydraulic calculation problem in soil and water conservation schemes,especially in areas lacking hydrological data and engineering experience.It also provided technological evidence for soil and water conservation engineering measure design on spoil dumps. |
