| 摘 要： | 通过埋置钢筋混凝土管约束爆破的竖向震动,采用延时爆破方式进行模拟天然地震的试验研究。讨论延时爆破峰值叠加问题,并对所取得的试验数据进行统计回归分析,给出能够预测适合本场地和本爆破方式条件下爆破震动的衰减规律的经验公式。研究结果表明,所得到的爆破地震波波形与天然地震波形较为一致,可较好地进行天然地震的模拟。

| Abstract: | The tests research of blasting vibration simulating earthquake were carried out by a reinforced concrete pipe embedded landscape orientation and hangfire.The issue of peak value superposing of hangfire was discussed.Based on the statistical analysis of measurement data obtained in this test,an equivalent explosive method was proposed,the equivalent was applied in this field and this blasting mode.The results show that the wave accepted from this test is similar to that of the natural one and the blasting method can be used to simulate earthquake. |
