大潭拱坝外掺MgO混凝土仿真计算分析

Simulation and analysis of Datan MgO-mixed concrete arch dam

在大潭拱坝仿真计算分析基础上,对外掺MgO混凝土快速筑拱坝技术的可行性、掺量选择、掺量分区设计等进行了分析研究,结果表明,外掺MgO混凝土快速筑坝技术是可行的,但从方便施工的角度考虑,全坝宜采用一个合适均匀的掺量.

Based on the simulation and analysis of the Datan concrete arch dam, an analysis is performed of the feasibility of the fast dam construction technology with MgO mixed concrete, rational amount of MgO, and partition design for the amount of MgO. The results show that the technology is feasible, while a rational and uniform mix ratio of MgO should be adopted for the whole dam from the angle of convenient construction.
