| 摘 要： | 深圳赤坳水库的大坝为浆砌块石重力坝,经过多年运行,材料参数已经发生变化。为反演大坝目前的弹性模量,首次采用支持向量机和粒子群反演方法进行对比研究,利用实测数据进行大坝弹性模量反演。两种反演方法结果接近,相互验证说明反演结果是正确的,同时也说明了上述两种方法在浆砌块石重力坝的反演分析工作中的可行性。

| Abstract: | The Dam of Shenzhen Chiao Reservoir is a concrete masonry gravity dam,and the material parameters have been changed af-ter years of operation.Based on measured data,this paper firstly uses support vector machine algorithm and particle swarm optimization to inverse the current elastic modulus of the dam.The results of two methods are close,and can be authenticated by each other.It indi-cates that the inversion results are correct and the above two methods are feasible in the inversion analysis of concrete masonry gravity dam. |
