【摘要】 在地形、地貌及场地条件复杂的山区,历次地震中都会出现一些破坏异常的点或区域。分析其破坏原因,对于当地或类似情况的点或区域的抗震设防以及减少由于地震造成的灾害损失具有重要意义。本文主要针对2014年盈江"5.24"和"5.30"地震后,Ⅷ度区的卡场镇五排村吾排小学二层框架教学楼的破坏情况进行分析,找出了造成建筑结构破坏的几个不利因素,主要包括山丘顶部地形放大效应、土层的放大效应、边坡效应以及多次地震灾害的累加效应。更多还原

【Abstract】 It is common that one abnormal damage appeared due to the complicated mountainous topography and site conditions during earthquake. It is of great significance to analyze the abnormal damage causes for seismic fortification of local or similar area,which will reduce the economic losses by earthquake disasters. Several adverse factors for abnormal earthquake damage of two-story frame structure in Wupai elementary school during"5.24"and"5.30"Yingjiang earthquakes were discussed,including the effect of hill terrain amplification,soil amplification,slope amplification and accumulative effect by multiple earthquakes.更多还原
