摘要
本文用试验的方法研究碾压混凝土重力坝在地震荷载作用下的破坏特性。在初始裂缝出现时坝体总体上仍处于弹性阶段的基本假定下，通过在龙滩大坝抗震动力破坏试验结果中考虑几种重要的影响参数并引入相应比例系数，使模型动力破坏试验的结果可直接定量地换算到原型上，从而在碾压混凝土坝的抗震安全性评估方面作了新的探索并提高了大坝抗震安全性评估的准确性。
The seismic failnre characteristics of Longtan Roller Compacted Concrete (RCC ) Gravity Dam are investigated by using dynamic model failure tests in this paper.Based on the11ypothesis that the dam generally remains elastic at the time of initial crack happening,several important proportional coefficients and effecting parameters are introduced in the suggested algorithm,which converts the experimental results to the proto type dam. Therefore,the seismic safety evaluation of Longtan RCC Gravity Dam is more reasonable and reli-able.
