【摘要】 通过对深圳地铁隧道爆破开挖时爆破震动监测数据的分析和研究,总结出爆破震动对地表建筑物产生危害的主要影响因素,并根据现场测定数据,拟合出地震速度、药量大小与爆源距离之间关系式。现场测定结果与研究表明,必须重视地铁隧道爆破地震规律及其对各种建筑物和构筑物影响的研究,才能充分发挥爆破技术的经济效益和最大限度地降低爆破振动的危害。更多还原

【Abstract】 Based on analyzing Seismic velocity and frequency of the main control factors of them, according to the data measured on surface buildings when Shenzhen Metro tunnels blasting digging, the relation formula among Seismic velocity and dynamite and the distance between blasting fountain can be obtained. Effects on buildings produced by vibration frequency and differences between blasting earthquake and natively seismic can be analyzed. The results of tests and research indicate that we must attach importance to blasting seismic rules and effects on different buildings in order that make basting techniques bring much economy benefits and reduce harm of blasting vibration as possible as much.更多还原
