摘要

根据现场实测数据,对重车运行引起的周边建筑振动实况和振动特性进行了分析研究。结果表明,地面振动Z振级主要由测点到道路中心的水平距离决定,在距线路一定距离时,车辆的载重对地质点振动的影响为非敏感因素。重车运行对结构虽不易构成安全影响,但对邻近建筑物的振动影响常造成环境振动污染问题。
The features of the environmental vibration induced by heavy trucks transit are studied by in situ experimental method.The analysis results suggest that the degree Z direction environmental vibration is controlled by the level distance from road,and at certain distance away from road,the weight of the trucks is the insensitive factors for environmental vibration.It is not easy to induce the near building damage by the environmental vibration induced by heavy trucks transit,but it must be attention for the effects of the pollution of environmental vibration.
