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 and mass concrete with thin-walled hollow pier as the research object, the temperature and stress inside the concrete under different construction conditions are simulated by computer FEM program to study the safety factor of crack resistance of concrete under different construction conditions, Provide a theoretical basis for temperature cracks.
