摘　　要：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。With reference to a practical project, finite element model was established using ABAQUS software to analyze the main reasons that cause cracks of cement floor with heating pipes. Four analysis scenarios were proposed and shrinkage stress of the cement floor with heating pipes were analyzed and compared for these four scenarios. It is concluded that the construction joints can significantly reduce the shrinkage stress and control the floor cracking.
