地形对振动压路机激发地震波传播的影响
|
摘要
为了治理振动压路机在施工中对建筑物的影响,对振动波进行监测,通过试验数据的回归分析,得到压路机地面振动衰减规律和高差地形的振动效应。结果表明,地面振动波传播衰减规律符合负幂指数函数的形式;负高差地形会产生振动"缩小"效应;高差地形对振动波传播的影响存在距离限制。
In order to control the vibration effects produced by vibration roller on buildings during the construction process,the vibration wave is monitored,the regression analysis for the experimental data is conducted and it is found the roller ground vibration attenuation law and seismic effect of elevation terrain.The results show that ground vibration wave propagation attenuation law conforms to negative exponential function form,negative elevation terrain will produce vibrations "zoom out"effect and there exists distance limitation in the effect of elevation terrain on vibration wave propagation.
