城市隧道开挖爆破震动的反应谱分析
|
摘要
结合青岛海底隧道开挖爆破振动监测的加速度时程曲线,利用MATLAB程序计算得到该地区爆破地震的加速度反应谱、速度反应谱和位移反应谱曲线,为该地区抗爆破地震设计提供了依据.并利用反应谱来研究爆破地震效应,研究成果对指导青岛后续地铁隧道工程开挖和保证地表建筑物安全有重要参考价值。
Based on the acceleration-time curve monitoring of Qingdao undersea tunnel excavation blasting vibration,the acceleration response spectrum,the velocity response spectrum and the displacement response spectrum were derived through the calculation using MATLAB program,which provide basis for anti-blasting seismic design of Qingdao area.The response spectrum was used to study the blasting earthquake effect,and the research results are of important reference value to the guidance of Qingdao subway tunnel excavation and to the ensuring of the ground building safety.
