ABSTRACT

The aim of the present study is to investigate the stability of a new cost-efficient dam structure, which makes use of materials to reduce the size of the traditional dam. The new dam structure is termed as concrete-rockfill combination dam (CRCD), covering a downstream inclined rockfill body as well as an upstream concrete wall. Small-scale models of CRCD are conducted by shaking table. Two different types of seismic records are utilized as typical input peak ground motions in the tests. The presented results demonstrate seismic characteristics and lay a basis for the subsequent aseismic design of CRCD.

混凝土-堆石组合坝稳定性试验

摘要

本研究的目的是调查一种新的具有成本效益的大坝结构的稳定性，该结构利用材料来减小传统大坝的尺寸。新坝结构被称为混凝土-堆石组合坝 (CRCD)，覆盖下游倾斜堆石体和上游混凝土墙。CRCD 的小型模型是通过振动台进行的。两种不同类型的地震记录被用作测试中典型的输入峰值地面运动。所呈现的结果展示了抗震特性，并为CRCD的后续抗震设计奠定了基础。
