【摘要】 通过对温州市西山东路塔下山石方爆破振动监测数据进行分析 ,采用线性、不耦合装药、孔内与孔外延时相结合的微差爆破方法有良好的减震效果。在对爆破地震波型分析后发现 ,段间时差以 75ms左右为最佳。测量的爆破地震波最大振动速度表明 ,石方爆破对周边建筑物的振动影响是安全的更多还原

【Abstract】 By analyzing the seismic data obtained from the soil blast engineering in East Way, Xishan WenZhou, it is found that the millisecond blasting can decrease the effect of the blast vibration. The blast seismic wave indicts that 75 ms is best to design the interval time in soil blast engineering. The vibration data confirms that the blast vibration’s effect on the surrounding buildings is safe.更多还原
