针对地暖管地面裂缝产生的主要原因,结合某实际工程,采用ABAQUS有限元软件,建立有限元模型,将模型划分为4种工况进行分析,对比4种工况下地暖管地面的收缩应力,从而得出设置界格缝能显著减小混凝土地面收缩应力,有利于地暖管地面混凝土裂缝控制。 Aiming at the main reason of floor cracks in floor heating pipes, a finite element model was established by ABAQUS finite element software based on a practical project. The model was divided into four working conditions for analysis. Comparing the shrinkage stress, It is concluded that setting the boundary crack can significantly reduce the shrinkage stress of the concrete surface, which is good for the control of the concrete crack in the floor heating pipe.
