工程卡车行驶诱发地面振动的实测分析

Measured Analysis of Ground Vibration Induced by Engineering Trucks

以工程卡车行驶产生的振动为研究对象,对郑州西四环植物园某路段进行实测。结果表明:重载卡车产生振动以竖向为主,且强度较低,竖向振动集中在10~20Hz低频段,水平向振动集中在60~70Hz的高频段;随着距离增加,振动幅值出现衰减趋势;该场地竖向振级均未超过《振动环境质量标准》(GB 10070—201X)(环境振动标准意见稿)中的允许限值。实测结果可为相关部门研究工程卡车地面振动传播特性以及控制该振动提供参考和依据。

Taking the vibration generated by the engineering truck as the research object,the actual measurement was carried out on a section of Zhengzhou West Fourth Ring Botanical Garden.The measured results show that the vibration of the heavy-duty truck is mainly vertical and the intensity is low.The vertical vibration is concentrated in the low frequency range of 10~20Hz,and the horizontal vibration is concentrated in the high frequency range of 60~70Hz.As the distance increases,the vibration amplitude appears attenuation trend;the vertical vibration level of the site does not exceed the allowable limit in the Vibration Environmental Quality Standard(GB 10070—201X)(Environmental Vibration Standards Draft).The measured results can provide reference and basis for relevant departments to study the ground vibration propagation characteristics of engineering trucks and control the vibration.
