摘要
通过运用层次分析法,以公路交通荷载诱发低矮砖混结构振动的影响为目标层;以人体舒适度和建筑物外观损伤为准则层;以车重、车速、地基土类型、建筑物距道路的距离、建筑物总高度、建筑物初始损伤和交通荷载作用次数为因素层,构建出层次结构模型。在专家打分法、构建数值模型及查阅已有文献等多种方式的基础上来对准则层、因素层中各因素进行对比分析并构建三标度判断矩阵。借助MATLAB程序对判断矩阵进行计算处理,得到公路交通荷载诱发建筑物振动对人体舒适度和建筑物外观损伤综合影响因素的排序。
By using (AHP),a hierarchical structure model is constructed,which takes the impact of road traffic load on the vibration of low-rise brick-concrete structure as the target layer,human comfort and building appearance damage as the criterion layer,vehicle weight,vehicle speed,type of foundation soil,distance between building and road,total height of building,initial damage of building and number of times of action of traffic load as the factors layer.On the basis of expert scoring method,building numerical model and consulting existing literature,the factors in criterion layer and factor layer are compared and analyzed,and the three-scale judgment matrix is constructed.With the help of MATLAB program,the judgment matrix is calculated and processed,and the ranking of comprehensive influencing factors of human comfort and building appearance damage caused by building vibration induced by highway traffic load is obtained.
