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,即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。
Based on the Kirchhoff principle, a calculation model for the vibration isolation system of existing buildings along the street was established and analyzed theoretically. At the same time, a shielding method was used in conjunction with a certain street construction project, ie, a shallow trench was used to insulate the flexible material to isolate vibration waves. The transmission method is to establish a vibration isolation system; and in combination with the actual situation of the project, vibration isolation materials are selected, and DASJ bridges and structure dynamic detection systems are used for “vibration isolation testing”. The results show that the building vibration isolation system proposed in this paper will greatly reduce the vibration of the building when the vehicle passes through, and has a good practical effect.
