九华山隧道爆破施工对明城墙振动影响的监测与分析
摘要
给出九华山隧道爆破施工对明城墙振动影响的监测方案,包括测振系统、测点布置、拾震器安装及测量参数的设定。介绍监测执行的依据和判别标准。基于爆破振动监测数据,对质点水平和竖向加速度、速度、位移及主频进行回归分析,确立振动传播衰减规律。分析不同药量爆破下各测点的波形主频率和药量相同、不同距离测点的加速度、主频及主频域,归纳出等距离测点、不同药量爆破振动的频谱特性和爆破地震波传播过程中频谱变化的特性,为类似工程提供借鉴。
The monitoring project on Ming Dynasty Wall vibration influenced by explosion construction of Jiuhuashan tunnel in Nanjing is set forth.The project includes vibration test system,measuring points arrangement,collecting sensor installation and test parameter enactment.The safety-judging standard of monitoring is introduced.Via regression analysis of main frequency,acceleration,velocity and displacement in horizontal and vertical directions of measuring points on the basis of monitoring data,the attenuation laws of spread of explosion vibration is put forward.The main frequency of explosion vibration wave of measuring points in different quantities of detonator is discussed.In the same way,the explosion vibration acceleration,main frequency,main frequency field of the measuring points in different distances to center of explosion are analyzed.The spectrum characteristic of explosion vibration measuring points in different quantities of detonator but in same distance to explosion center and the spectrum change characteristic in transmission of explosion vibration earthquake waves are concluded.These will provide references to the similar projects.
