【摘要】 以腾冲县太极桥景区顶管隧道爆破施工为背景,设计了腾冲县顶管爆破工程掘进断面的爆破参数,并进行现场爆破试验,根据最小二乘法原理对监测到的爆破震动速度进行回归分析,得到该场地的爆破地震波传播衰减规律。通过Fourier变换进行了爆破振动的功率谱分析,得到爆破振动能量分布的优势频率。更多还原

【Abstract】 Take the pipe-jacking blasting construction to Taiji bridge scenic area of Tengchong county as an example,the blast parameters of advancement was designed for excavation,and meeting blast test.The regression analysis of blasting vibration velocity was done by the least squares principle,and finally the law of blasting vibration propagation was obtained at this area.The lasting vibration was analyzed by Fourier transform power spectrum,and the advantages frequency of energy distribution of the blasting vibration was obtained.更多还原
