摘要
利用ABAQUS有限元分析软件,对地下室底板在施工过程中的温度和应力进行仿真模拟,得到底板温度场和温度应力分布规律,当温度应力值等于混凝土抗拉强度时,混凝土开裂,因此可以较为准确的预测开裂时间,并将有限元模拟结果与理论计算结果进行比较,得出规律一致。
The thermal field and stress of basement foundation slab at early age is analyzed by the finite element software of ABAQUS,through computer simulation,the law of thermal field and stress are given,and concrete will crack when stress is equal to the tensile strength of that time,so the simulation can froecast cracking time more accurately and compared the simulation and theoretic results, the law of temperature and stress are same.
