| 摘 要： | 介绍了一种在爆前即能预测建筑结构对爆破震动的响应的方法。通过预测结构地基的震动波形计算结构的抗震设计反应谱 ,用动力分析法计算结构在爆破震动作用下的响应。预测结果为结构所受内力的定量数值 ,并且还可通过不同延期时间下的预测结果比较 ,为爆破设计选取最佳延期时间。实际应用表明 ,预测结构可靠。此方法可用于预测结构在爆破震动作用下的安全性。

| Abstract: | A method that can be used to predi ct structural responses to blasting vibration was introduced in this paper.The s tructural response spectrum was computed using the seismogram of structural foun dation that has been predicted in advance.Then,the structural responses can be d erived by employing dynamic analysis method,and the optimum delay time can also be determined by comparing the predicting results under different delays.The mod el has been used in a practical blast,the predicting results are reliable.The mo del in this paper can be applied to evaluate the security of stuctures before bl ast. |
