摘要
以中博会展中心大体积承台的施工为例,探讨了大体积混凝土施工的温度控制措施;按平面应变理论建立了数值分析模型,利用有限元对大体积承台进行了温度场和应力场的模拟分析;对承台内部的混凝土温度进行了测量,并对实测结果进行了分析。
Taking the pile cap of China Expo Exhibition Center as an example, the specific temperature controlling measures of massive concrete construction are discussed. A numerical model is established according to the plane strain theory, and the temperature and stress field of pile cap are simulated and analyzed by finite element. In addition, the internal temperature of large pile cap concrete is measured and the results are analyzed.
