| 摘 要： | 对被爆破拆除的龙海大厦周围重要的保护目标进行了振动监测,在最近居民楼和省医院两个测点监测得到振动速度数据。对振动波形的时间历程分析认为记录的波形主要含有爆破振动、后坐振动及塌落振动三个阶段;对比分析这三种振动的速度及频率特征,得到以下结论:塌落振动比爆破振动的速度更大、频率更低、对周围建筑物的危害也更大,在楼房倒塌处保留一定厚度的建筑废碴并敷设沙包墙具有很好的减振效果。

| Abstract: | In the blasting demolition of Longhai building,vibration monitoring for the important buildings which needed to be protected from the affect of the collapsing was conducted,with the nearest resident building and a provincial-owned hospital being taking as two targeted protecting objects to collecting the monitoring data.The results from time history analysis of the vibration showed that the wave contained blasting vibration,back ward collapse vibration and collapsing vibration.Comparative analysis of the ch... |
