摘要
针对厦门市仙岳路至演武大桥某隧道工程开挖过程中引起临近建筑物墙壁产生裂缝及窗户玻璃被振动破坏的现象,结合爆破参数和振动速度的监测数据,对该建筑物做出安全评价。分析了可能产生破坏的原因,指出爆破施工中随时视现场情况调整爆破参数和考虑影响建筑物安全评估多种因素的一些建议。
Based on the rift of the close building and damage of window glass produced by tunnel blasting vibration from excavating the tunnel between Xiamen City Xianyue road and the Yanwu bridge and the data obtained by monitoring the detonation parameters and shaking speeds, the safety of the building is evaluated. The probable damage cause produced by vibration is analyzed. Some suggestion of adjusting detonation parameters at any time under scene condition and considering the various factors affecting the safety evaluation of this building are presented.
