Analysis of Mass Concrete Construction and Temperature Control of Raft Foundation
In order to improve the quality and safety of raft foundation engineering,ABAQUS finite element software was used to simulate and analyze the internal temperature field and temperature stress of mass concrete in a high-rise building project.The results show that the error between the simulated value and the measured value is 2%～5%,which indicates the reliability of the model.The variation of the internal temperature stress of concrete shows that the larger the thickness of concrete is easy to cause the crack of the bottom,and the smaller the thick-ness of concrete is easy to cause the crack of the surface of concrete.The dynamic curing method can effectively adjust the internal temperature change of concrete under proper mold temperature.On this basis,specific dynamic maintenance measures are put forward to avoid causing tem-perature difference cracks.
