摘要
结合施工过程,应用三维有限单元法,对龙滩大坝连续浇筑混凝土的温度及温度应力,进行仿真计算的研究。论述了加快施工进度,连续上升浇筑混凝土的可行性,必要条件及需要采取的温控措施。
Based on the actual construction, a study on the simulative calculation for both the temperature and the thermal stress of the continuous RCC placement for the construction of Langtan RCC Gravity Dam is made with 3-D finite element method. The feasibility, necessary condition and the measures for the temperature control for the continuous placement to speed up the construction progress is discussed herein as well.
