摘要
对某偏斜砖结构烟囱的爆破振动进行了测试,并对某些测点的振动速度值异常情况进行了现场调查,结合爆破振动测试结果,分析了该烟囱底部一侧存在软弱夹层,导致烟囱偏斜,引起爆破地震效应异常。指出了该爆破振动测试系统对类似爆破振动效应分析及其安全防护的重要意义。
Did the test for the blasting vibration of a leaning brick-structural chimney,and did the site investigation for the abnormal condition of some measuring points 'vibration speed data,combine the test result of blasting vibration,analyze the season of chimney leaning and cause abnormal of blasting seismic effect is that there is a weak interlayer on one side of this chimney's bottom.Points out the significance of this blasting vibration measurement system to analysis on similar blasting vibration effect and its safety protection.
