| 摘 要： | 复杂坝基弹塑性力学参数反演的计算工作量直接取决于采用何种优化方法。根据大坝在运行期的实测资料，运用有限元正交数值试验、回归分析和优化相结合的方法，反演了坝基岩体的弹塑性力学参数。实例研究表明了该方法的有效性和实用性。

| Abstract: | The time consumption of back analysis of elastoplastic mechanical parameters of complex dam foundation is directly dependent on the optimization methods selected.In this paper the back analysis of mechanical parameters was conducted by means of combination of FEM orthogonal numerical experimentation,regression analysis and optimization on the basis of the measured displacements during the operation period.The case study revealed the efficiency and practicability of this method. |
