| 摘 要： | 为了对施工振动的产生和传播过程进行合理的预测,并对施工振动产生的环境影响进行科学的评价,利用大型有限元模拟软件ABAQUS建立了经过合理简化的强夯施工的ABAQUS有限元模型.依据模拟得到的质点峰值速度,应用单因素参数评估方法,以瑞典振动控制规范作为标准对强夯加固项目的施工振动环境影响进行了评价.依据模型得到的预测结果与实测数据对比取得的一致性,模型的有效性得到了验证,评估结果显示强夯施工对周围环境的危害处于可接受范围.其预测评价方法和参考标准均对中国施工振动环境影响评估方法的完善有一定的参考价值和指导意义.

| Abstract: | To predict the generation and transmission of construction vibration and evaluate its impact,a simplified model for the dynamic compaction operation has been built using ABAQUS simulation software.Based on the peak particle velocity obtained from ABAQUS model,using the single parameter method,the impaction of dynamic compaction vibration is evaluated according to the Swedish vibration control standard.The model is validated by the comparison of the prediction results and the measurement data.The evaluation shows that the impact of construction vibration is acceptable.The prediction and evaluation methods and the Swedish vibration control standard are useful for improving the evaluation on construction vibration and the vibration control standard in China. |
