为了解决混凝土因干缩导致的开裂,需分析计算混凝土内部湿度情况。根据室内试验实测的湿度值,运用遗传算法和粒子群算法对混凝土试块湿度场进行反演计算,得到反映混凝土湿度扩散性能的参数。利用这些参数和三维有限元仿真计算程序对湿度场进行分析,将计算值和实测值进行对比得知二者变化规律一致,但粒子群算法相比而言减少计算时间且计算精度较高,可用于指导施工。
In order to solve the cracking caused by shrinkage of concrete, it is necessary to analyze and calculate the humidity inside the concrete. According to the humidity measured in indoor test, the humidity field of concrete block is calculated by genetic algorithm and particle swarm optimization algorithm, and the parameters that reflect the humidity diffusion of concrete are obtained. Using these parameters and the three-dimensional finite element simulation program to analyze the humidity field, comparing the calculated value with the measured value, we know that the two have the same variation rule, but the PSO reduces the calculation time and the calculation precision is higher To guide the construction.
