【摘要】 通过对新疆精河5.0级地震现场调查,分析了灾区局部场地效应及房屋震害特征,对震害特点进行了较为全面的分析总结。震害调查显示,灾区房屋主要以老旧的土坯房为主,地震作用使本身老旧的房屋裂缝加宽,破坏加重。同时,受局部场地差异影响,灾区房屋震害具有明显的南北分带的特点。另外,根据地震现场考察,此次地震的发震构造为库松木楔克山前断层,该断裂是发育在北天山山前逆冲推覆体前缘的一条全新世活动断层,沿断裂断错晚更新世以来的各级地貌面和沟谷阶地,并在地表形成断层陡坎和古地震地表变形遗迹。更多还原

【Abstract】 According to earthquake site investigation of Jinghe earthquake with MS 5.0,the authors analyze site effects and characteristics of earthquake hazards in earthquake-striken area and summarizes features of earthquake damage.It has been showed that: most buildings in the earthquake-striken area were adobe building;they were severe damaged by earthquake;the damage building showed south-north zonation;the seismogonic structure was Kusongmuqike piedmont fault which was a Holocene active fault and dislocated the valley of Late Palaeozoic stratum,formed fault scarp and surface deformation on the ground.更多还原
