广西靖西MS5.2地震震害特征

Disaster Characteristics of the Guangxi Jingxi MS5.2 Earthquake

  • 摘要: 通过对广西靖西MS5.2地震灾区走访调查及开展烈度评定、损失评估等现场工作,发现宏观震中位于靖西市湖润镇,极震区烈度为Ⅵ度,震区位于中越两国交界处;地震为主余型地震,余震超过百次;震区房屋结构类型主要为砖混结构,部分墙体出现“X”裂缝,门窗洞角出现斜向裂缝、竖向裂缝或水平裂缝,装修层局部脱落等;土(砖)木结构出现掉瓦、梭瓦等现象;地震引起多处崩塌、山石滚落等次生地质灾害。

     

    Abstract: Through visiting survey and in intensity assessment, loss assessment and so on field work in the earthquake-stricken area of Guangxi Jingxi MS5.2 earthquake, it is found that the macro-epicenter of the earthquake was located in Hurun town, Jingxi City, its intensity of the meizoseismal area was of magnitude Ⅵ; The earthquake area was located at the border between China and Vietnam; The earthquake sequence belongs to main shock-after shock type with more than a hundred aftershocks. The main type of building structure in earthquake area is brick-concrete structure with "X" cracks appear on some walls, oblique cracks, vertical cracks or horizontal cracks appear at the corners of doors and windows, and the decoration layer partially falls off. The phenomenon of falling and sliding of tiles appears in civil and brick-and-wood structures; The earthquake caused many secondary geological disasters, such as collapse, rockfall, etc.
