摘要
结合带式落锤机车间振动状况的实测数据,通过比较已列入规范的两种地面振动衰减公式的拟合结果,确定本场地条件下的近源振幅衰减计算公式,并提出利用实测信号预测近源地面竖向振动的公式。
There are two formulas having been placed into criterions for calculating attenuation of ground vibration. Based on an actual measurement of the vibration in a belt drop hammer workshop, the near-source amplitude attenuation formula under the local field condition is chosen by comparing the two fitting formulas.The formula for calculating near-source ground vertical vibration is then suggested.
