沿街既有建筑物隔振体系的开发应用

运用基尔霍夫原理,对沿街既有建筑物隔振体系建立计算模型,进行了理论计算分析;同时,结合某沿街建筑工程采用屏蔽法,既采用浅沟中填嵌柔性材料来隔绝振动波的传递的方法建立隔振体系,并结合该工程实际情况选取隔振材料,利用DASJ桥梁与结构动态检测系统进行“隔振对比测试”。结果表明,本文所建议的建筑物隔振体系将大幅度降低车辆通过时对建筑物所产生的振动,实用效果良好。

Application of Vibration Isolation System for Existing Building along a Street

A caculative model of the vibration isolation system fo r existing buildings along a street has been built by the principle of Kirchhoff to make analyses and calculation. In a construction project,the method of compa rtment shield,in wiich the vibration was isolated by a slow fossa infilled with soft materials, has been used. The result of "contrast test of vibration isolat ion " by the dynamic analysis signal of bridges and structures has shown that v ibration isolation system proposed in the paper can greatly reduce the vibration that passing trucks bring to buildings which practical effectiveness .
