摘要
中国是最早开展混凝土坝施工仿真分析计算研究的国家之一。混凝土坝温度应力计算由最初简单的二维平面问题发展到后期复杂的三维问题,随着计算机技术的进步及相关理论研究的深入,演变为可以模拟混凝土坝整个浇筑过程的施工仿真分析计算。因为对边界条件、施工过程、温控措施及坝体结构更为真实的模拟,遇到了计算量巨大,计算效率低下及计算精度不高的问题。在众多科研院所不断研究攻克所遇到难题的时候,新的数值方法的出现也为施工仿真分析计算提供了新的发展空间。
China is one of the earliest countries which carried out concrete dam construction simulation analysis and computation.The concrete temperature stress computation began from the simplest 2 dimensional plane issue in early time to complicated 3 dimensional issues in later stage.Along with development of computer technology and relative theory research,the whole grouting process of concrete dam can be simulated.In order to simulate boundary condition,construction process,temperature control measure and dam body structure more truly,the problems of giant computation quantity,low computation efficiency and computation accuracy are encountered.While encountered difficulty in the successive research by multiple research institutes,new digital approach provides new development space for construction simulation computation.
