摘　　要：大体积混凝土浇筑过程中,由于水化热的产生使得混凝土结构产生内外温差。如果温差过大,混凝土结构表面会产生温度裂缝,对结构的安全稳定非常不利。利用大型通用结构分析软件ANSYS分析比较了影响船坞坞口大体积混凝土结构浇筑过程温度场的部分因素,可供类似大体积混凝土在施工浇筑过程中参考。In the process of mass concrete pouring, the hydration heat generates the temperature difference between the inside and outside of the concrete structure. [f the temperature difference is too large, the temperature crack will be produced in the surface of the concrete structure, which is very adverse to the structure＇s safety and stability. This paper analyzes part factors affecting the temperature field of the mass concrete during pouring by software ANSYS, which may serve as a reference for mass concrete pouring construction.
