摘　　要：通过对施甸 5 9级地震震害现象的机理分析 ,清晰地发现竖向地震作用起重要破坏作用 ,与获取的强地面运动峰值加速度竖向值相吻合。映证了在历次地震中许多地震工作者常发现极震区竖向地震力起重要破坏作用的原因。Through the mechanism analysis of seismic disasters of M5.9 Shidian earthquake, it is clearly found that the vertical earthquake function has played an important role in the damages, which is identical with the vertical value of the peak acceleration of strong ground motion. It proves the damaging causes that the vertical earthquake force has played, for which the seismologists have discovered its important role in the magistoseismic area.
