摘要

在深覆盖层地基上修建高土石坝，其防渗体系的可靠性是一项关键技术问题。针对瀑布沟水电站堆石坝的实际工程特点，应用自适应有限元方法，分析研究了大坝的稳定性和覆盖层中混凝土防渗墙与坝内黏土心墙接头部位的局部应力和变形情况，对比分析了不同接头形式的利弊，为设计部门推荐了合适的接头形式。

Abstract

The reliability of seepage prevention system is a key problem for high rockfill dam built on the foundation of large overburden depth. Considering the practical characteristics of Pubugou Hydropower Project

the stability of the dam

the deformation and the stresses of the joint zone connected the core wall in the dam and the concrete cut wall in the large overburden depth are analyzed by the adaptive finite element method. And then the advantages and disadvantages of the different type of joints are also discussed; finally

an appropriate type of joint is recommended to the designers.
