高拱坝真实工作性态仿真的理论与方法

Theory and method on simulation of actual working performance of high arch dams

高拱坝的安全是坝工界非常关注的问题,其中的核心问题之一就是大坝在当前荷载工况下的真实工作性态。本文从高拱坝真实荷载、分析方法与技术、参数与准则等3个方面就近几年来取得的有关高拱坝真实工作性态仿真的理论与方法的成果进行系统的阐述,建立起高拱坝真实工作性态仿真研究的整体概念,服务于高拱坝的设计与施工。

Safety of super-high arch dams is a crucial subject in hydraulic structure design, and one of its key issues is how to evaluate the actual working performance under the existing loading conditions. This paper presents a comprehensive discussion on the theories and methods of this issue developed recent years, from three aspects of actual loading, analysis methods and techniques, and parameters and criteria, so as to formulate a general concept of high arch dam simulation for the design and construction of high arch dams.
