Abstract：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.
