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。
Take the pipe-jacking blasting construction to Taiji bridge scenic area of Tengchong county as an ex- ample, the blast parameters of advancement was designed for excavation, and meeting blast test. The regression analy- sis of blasting vibration velocity was done by the least squares principle, and finally the law of blasting vibration prop- agation was obtained at this area. The lasting vibration was analyzed by Fourier transform power spectrum, and the ad- vantages frequency of energy distribution of the. blasting vibration was obtained.
