以杭州某软土基坑为背景,通过在基坑周边地表布置加速度传感器,对重载车辆行驶引起的软土地区表层土体振动进行测试,得到软土地区临时施工道路的振动响应。通过统计各测点的加速度平均峰值、加速度振级以及振动主频,分析了软弱土体的振动响应,获取不同车速、测点方位等对土体振动响应的影响,根据重载车辆荷载对土体振动加速度以及振级随着离振源距离变化趋势最终划分基坑周围受重载车辆行驶振动的影响范围,得到软土地区基坑安全施工的范围。通过本次对杭州某软土基坑周边振动测试有助于全面认识重载车辆行驶振动对土体振动的传播规律,并对软土地区的基坑工程设计、安全施工及防灾减灾等提供依据。

Taking a soft soil foundation pit in Hangzhou as the background,the vibration of surface soil in soft soil area caused by low-frequency heavy-duty vehicles was tested by arranging acceleration sensors on the surface around the foundation pit,and the vibration response of temporary construction road in soft soil area was obtained. By counting the average peak acceleration,acceleration vibration level and dominant frequency of vibration at each measuring point,the vibration response of soft soil was analyzed,and the influence of different vehicle speed and measuring point orientation on the vibration response of soil was obtained. According to the change trend of the acceleration and vibration level of the soil vibration caused by the heavy vehicle load with the distance from the vibration source,the influence range of heavy-duty vehicle driving vibration around the foundation pit was finally divided,and the safe construction range of foundation pit in soft soil area was obtained. The vibration test helps to fully understand the propagation law of heavy-duty vehicle vibration,and further provides basis for foundation pit engineering design,safe construction and disaster prevention and mitigation in soft soil area.
