摘　　要：新疆伽师—岳普湖5.8级地震宏观震中位于岳普湖县的铁热木乡和兵团农三师42团的北面,震中烈度为 度。本次地震影响范围位于巴楚—伽师6.8级地震 — 度影响区域内,累计破坏效应造成了较为严重的房屋破坏。通过对大量震害资料和强震记录的分析,根据建筑物的破坏情况和场地峰值加速度衰减特征,在尽可能排除累计破坏效应的基础上确定了地震烈度分布,分析了不同烈度区中的建筑物结构破坏特点及其与地震动影响场的关系。The macroscopic epicenter of the Jiashi-Yuepuhu earthquake with M_S5.8 in Xinjiang is situated on the north of Tieremu village belonging to Yuepuhu county and the 42^(nd) regiment belonging to the third georgic division. The intensity of the epicenter is Ⅶ. The area of influence about the earthquake lies in the influence region of the Bachu-Jiashi earthquake with M_S6.8 and the intensity Ⅵ-Ⅶ.The cumulative damage effect resulted in the severe damage of the building. By analyzing many data of the seismic disaster and recordings of strong earthquakes, according to the damage of the building and the attenuation characteristics of the peak value acceleration in field, basing on removing the cumulative damage effect as possible, we made sure the distribution of the seismic intensity. And analyzed the construction damage feature in different intensity areas and the relation between it and the effect field of the ground vibration.
