面板堆石坝混凝土面板一次性施工仿真研究

Simulation study on a single time construction of the concrete deck for a CFRD

对面板一次性施工问题进行了初步探讨,通过对面板结构受力分析,在理论上得出了面板不开裂的条件,解决了特长混凝土面板不开裂这一关键技术问题,论证了堆石坝面板一次性施工是完全可能的.提出了一个可行的研究方向,对全面认识面板结构受力,进而采取相应保护措施,避免或减轻面板遭受各种力的破坏,指导堆石坝面板一次性施工具有重要的意义.

A preliminary exploration of the problem of constructing the concrete deck of a CFRD is presented. The analysis of load action has permitted to determine theoretically the conditions of the deck non-cracking performance and this helps resolve the most important technical problem of an overlong deck, thus proving the full possibility of constructing the deck for a single time. Some aspects to be researched are suggested to understand comprehensively the load action of a deck to take protective measures, and to avoid unnecessary destruction of the deck. All this will be of great significance for guiding the construction of the deck for this type of dam.
