【摘要】 基于某地下室承台及底板大体积混凝土的配合比设计、材料参数、混凝土施工、养护全过程及其实测温度等资料,采用ANSYS有限元软件建立模型,通过施加大气温度及热荷载,对其温度场进行计算分析,揭示了该类大体积混凝土裂缝的开展机理,可作为预测混凝土裂缝发展的依据。更多还原

【Abstract】 Taking the practical engineering as an example, based on the design of mix proportion, the material parameters, the whole process of construction and curing of concrete and the measured temperature of cushion cap of basement and floor of mass concrete, the model is established by ANSYS. The temperature field is calculated and analyzed by applying the atmospheric temperature and thermal load, the development mechanism for cracks of mass concrete is revealed, which can be used as a basis for predicting the development of concrete cracks.更多还原
