摘要
旁多水利枢纽工程规模大,设计地震烈度高,坝基覆盖层深厚且地处高海拔地区,坝基防渗型式的确定是涉及工程安全与否的关键技术问题。文章首先论述了该工程坝基防渗设计方案的拟定,然后针对各方案进行了渗流计算,分析坝基覆盖层的渗流及渗透稳定特性,为坝基防渗设计方案的确定提供依据。
The seepage type of dam foundation is key technique issue to affect the project safety for the Pangduo hydro -junction project. The project is located at high altitude area and has the large scale, the high design earthquake intensity and the thick overburden layer. The paper introduces the determination of the seepage design scheme for dam foundation, analyzes the seepage and permeability stability of overburden layer of dam foundation based on the seepage calculation of each scheme, which provides basis for the determination of seepage design scheme of dam foundation.
