摘　　要：建筑物的外部承压分布的准确检测是危房鉴定的基础,十分重要。建筑物外部承压呈现一定的压力移动性,承受的压力随着外部环境的变化,压力分布区域的计算中心点容易产生随机的移动。传统的建筑承压计算方法进行建筑物承压检测时,需要根据固定压力区域计算建筑物的承压中心区域,一旦承压区域中心发生变化,会造成中心承压寻优计算过程速度慢,无法获得准确的计算结果。提出基于改进遗传算法的建筑物承压检测方法,对遗传算法的选择算子、交叉算子和变异算子分别进行了改进,利用快速收敛的特征对计算过程中的承压移动进行消除,添加确保能够检测到建筑物存在的承压异常区域,获得准确的承压异常区域分布信息。仿真结果表明,利用改进遗传算法具有良好的收敛性,能够准确检测出建筑物的承压区域分布情况。In this paper, an pressure-bearing detection method of building was proposed based on improved genetic algorithm. The selection operator, crossover operator and mutation operator of genetic algorithm were improved respectively. The pressure-bearing movement in calculation process was eliminated by using the characteristic of rap- id convergence. Meanwhile, abnormal pressure-bearing region existed in the building which can ensure to be detec- ted was added to obtain the accurate distribution information of abnormal pressure-bearing region. Simulation results show that using the improved genetic algorithm with good convergence can accurately detect the pressure-bearing re- gion distribution information of a building.
