拱坝反分析的多点拟合法

Multipoint quasi-coincidence method of inverse analysis for arch dams

本文提出了基于优化理论的拱坝反分析的多点拟合法。实现了位移的计算值与实测值的多点拟合,且可同时反演坝体多个弹性模量及坝基多个变形模量,文中还给出了多组反演算例,达到了13点拟合,计算成果表明:本法是可行的、有效的。

In this paper, multipoint quasi-coincidence method of inverse analysis for arch dams based on optimum theory is presented. Multipoint quasi-coincidence of computed displacements with measured displacements is reached. Elastic modaules of dam and deformation modules of foundation can be simultaneously inversed. Examples showing the inverse analysis are also given, and thirteen points of quasi-coincidence are achieved, The computed results witness that the method is feasible and effective.
