| 摘 要： | 基于混凝土绝热温升数据，对平海湾风电基础承台大体积混凝土在施工过程中的温度应力场进行全程仿真计算。通过对比分析有、无冷却水管条件下承台混凝土结构的温度应力场，说明布置冷却水管效果显著，能有效降低承台混凝土内部最高温度及内、外表温差，以仿真分析结果指导基础承台混凝土的设计与施工，能有效防止混凝土开裂，提高施工质量。

| Abstract: | Based on the adiabatic temperature rise data of concrete,we carry out a whole-process simulation and calculation of the temperature stress field of mass concrete during construction of the wind power foundation platform of the Pinghai Bay. By comparing and analyzing the temperature stress field of the concrete structure under the condition of cooling water pipe or not,we know that the effect of the cooling water pipe is obvious,and it can effectively reduce the temperature difference between the temperatures inside and outside and the highest inside temperature.The simulation results can guide the design and construction of wind power foundation platform,prevent cracks effectively,and improve the construction quality. |
