摘要
针对公明水库大坝防渗加固4个备选方案,综合考虑施工难度、建设成本以及防渗质量等多重因素,构建了多准则评价模型,采用层次分析法和熵权法组合赋权法对指标赋权,确定了坝基帷幕灌浆方案为优选方案,并对该方案进行了坝体渗流稳定性分析。结果表明,公明水库大坝防渗加固后在防渗性能和抗滑稳定性方面均达到了规范要求。
Four alternative seepage prevention and reinforcement schemes for the dam in Gongming Reservoir are compared.Taking into account multiple factors such as construction difficulty,construction cost and seepage prevention performance,a multi criteria evaluation model is constructed.Then,the analytic hierarchy process and entropy weight method are combined to determine the weight of each indicator.The dam foundation curtain grouting scheme is selected as the optimal scheme.The seepage stability of the dam is then analyzed.The results show that both the seepage prevention performance and the anti-sliding stability of the dam meet the standard requirements after the reinforcement.
