薄壁空心墩底座高强大体积混凝土温控计算研究

Calculation Research on Temperature Control in High Strength Massive Concrete of Base of Thin-Walled Hollow Pier

以薄壁空心墩底座高强大体积混凝土为研究对象,采用计算机有限元程序模拟计算不同施工情况下混凝土内部的温度和应力,研究不同施工情况下混凝土的抗裂安全系数,为实际施工中防止混凝土产生温度裂缝提供理论依据。

Taking the high strength massive concrete of base of thin-walled hollow pier as the research target, the temperature and stress in concrete under different constructions conditions are simulated by computer technology and the anti-cracking safety efficiencies are also studied. All these offere the theoretical basis for the temperature cracking control in the concrete.
