水下强爆破的近场地面运动观测与分析

Analysis and Measurement of Ground Motion at Underwater Blasting of Port NanTon

通过对南通港主航道水下除障强爆破的观测，结合爆炸地震波理论，分析了爆破近场地面运动的特点，指出经验公式估算值与实际观测结果在评价地面运动对场地及地表建筑安全性评价的意义。

In this paper, based on analysis and measurement of ground motion at underwater blastingdemolishing of port NanTon and analysis for characterisitic of ground moion by seismic wave,discussed relation between empiric formula and field measurement data at evalate of Safety ofbuldings in the ground motion.
