三维有限元渗流模拟计算在蟒河口水库防渗设计中的应用

The Use of Three-dimensional Finite Element Influent Analogue Computation in the Design Against Leakage in the Manghekou Reservoir

蟒河口水库工程天然来水量较小,开发目标高。采取有效的防渗处理措施才能保证水库开发要求的蓄水量。在本工程中,采用三维有限元渗流模拟计算对防渗处理措施进行复核。根据对计算结果的分析,对防渗措施进行调整、优化,确定最终的经济、高效的防渗方案。通过工程经验类比,本次计算采用的方法、最终的结果是满意的。

The natural water inflow of the Manghekou reservoir project is s mall, but the development goal is high. The effective guards against leakage are necessary to guarantee the water-holding capacity of the reservoir development request. In this project, The ＂three dimensional finite element influent analogue computation＂ are adopted to check that if the guards against leakage are effective or not. According to the analysis of the computed results, Several rectifications and optimization in the methods against leakage can be made, and make sure that they are economical, highly effective guards against leakage. Contrasting with other projects, The methods adopted in the computation and the results are satisfied.
