摘要
In this paper, a gravity dam model with a geometric scale of 1: 100 is applied. The low elastic modulus and low-strength concrete simulation materials which satisfy the elastic-gravity similarity rate and the metal materials which satisfy the similar relationship of the reinforcement ratio are applied. The comparative shaking table model tests of concrete gravity dam with and without reinforcement are carried out by applying artificial waves and Lijiang waves and Qianan waves respectively, and the effect of seismic reinforcement is verified quantitatively according to the similarity ratio. Experimental results show that although aseismic reinforcement has little effect for the initial crack of dam sections, the fast spreads of the cracks are obviously restricted after the crack occurs in the dam. The results are valuable for engineering in high-intensity seismic regions. © 2019, Editorial Department of JVMD. All right reserved.
