中家湾隧道爆破振动监测与分析

摘要

The paper undertakes the supervision of blasting monitoring at Zhongjiawan tunnel blasting,concludes K and α value by adopting the least square regression analysis based on Matlab,and calculates the maximally allowed charge weight at single section when the blasting vibration achieves the safety vibration velocity according to the blasting vibration law achieved by K and α value,so as to ensure the safety of the high-voltage tower.%在中家湾隧道爆破施工过程中进行了爆破振动监测,应用基于Matlab的最小二乘法的回归分析得出了K,α值。根据K,α值获得的爆破振动规律估算出爆破振动达到安全振速时的单段最大允许装药量,以确保高压电塔的安全。
