大体积混凝土体积大、结构复杂,很容易出现裂缝。为了使大体积混凝土温度应力仿真分析与实测结果更加接近,提高仿真计算的精度,在沉箱底板布置了温度和应力测点,将实测结果与仿真分析结果进行对比,通过调整仿真计算参数。结果表明,仿真计算结果能够与实测值比较接近。 Large volume of concrete bulky, complex structure, it is easy to crack. In order to bring the mass temperature stress and stress measurement closer to the measured results and improve the accuracy of the simulation calculation, temperature and stress measuring points are arranged on the caisson floor. The measured results are compared with the simulation results and the parameters are adjusted by adjusting the simulation. The results show that the simulation results can be compared with the measured values.
