【摘要】 为避免隧道施工爆破过程中对周围构筑物产生危害,结合巩登高速北庄隧道工程施工,采用美国生产的REFTEK130B型地震仪与英国生产的GURALP三分量地震计,对北庄隧道左右线隧道在不同用药量条件下的地表监测点的最大振动幅值与加速度进行了测试,并根据爆破震动监测结果,指导了北庄隧洞施工组织设计,控制施工爆破对隧道上方北庄村房屋的影响,取得了良好效果。更多还原

【Abstract】 In order to avoid the damage for surrounding constructions caused by the blast during the tunnel construction,combined with the construction of Beizhuang Tunnel of Gongdeng Expressway,the maximum amplitude and the acceleration of surface test spots for the left and right line of Beizhuang Tunnel with different quantity of explosives were tested,and this work was finished with the seismographs(type:REFTEK130B,made in America) and the radio detector(made in Britain).The test result of blast vibration instructed the design of the construction organization of Beizhuang Tunnel,controlled the effect for Beizhuang village located in the top of Beizhuang Tunnel from the construction blast,and it did well.更多还原
