摘要
北坑水库坝型为面板堆石坝,大坝左岸基础存在10~30 m厚覆盖层及全风化凝灰岩,若采取全挖方案,开挖及坝体填筑工程量显著增大。工程实际情况,考虑利用坝基覆盖层及全风化岩体。采用有限单元法及刚体极限平衡法计算大坝及基础的稳定、应力变形,论证大坝基础保留方案的可行性及其他工程处理措施的必要性,相关成果为类似地区面板堆石坝设计提供参考。
The dam type of Beikeng Reservoir is a face rockfill dam. There are 10 ~ 30 m thick overburden and completely weathered tuff on the foundation on the left bank of the dam. If the full excavation scheme is adopted, the quantities of excavation and dam filling will increase significantly. According to the actual situation of the project, the dam foundation overburden and completely weathered rock mass are considered. In this paper, the finite element method and rigid body limit equilibrium method are used to calculate the stability, stress and deformation of the dam and foundation, and demonstrate the feasibility of the dam foundation retention scheme and the necessity of other engineering treatment measures. The relevant results provide a reference for the design of face rockfill dam in similar areas.
