摘要
四川属多山区,又是地震高发的地区,近些年发生了包括汶川8.0级地震、芦山7.0级地震及九寨沟7.0级地震等数次7级以上大地震,地震引发了大量的地质灾害,对灾区造成了的巨大的破坏。地震所形成的地裂缝,是地震引发次生地质灾害的一种,对地震灾区的建筑物特别是对山区输电线路影响较大。本文根据近些年四川地震灾区典型地段地震地裂缝统计,分析了地震地裂缝类型、分布特征、性质及对输电线路的影响,并对工程处理措施进行了探讨。
Sichuan is a mountainous area,where earthquakes are common,including the Wenchuan 8.0 earthquake,Lushan 7.0 earthquake and Jiuzhaigou 7.0 earthquake.The earthquake caused a lot of geological hazards,and earthquake caused great damage to disaster areas.The ground fissures formed by earthquakes are a kind of secondary geological disasters.In this paper,according to the earthquake-stricken area in sichuan in recent years the typical section of earthquake ground fissures,analyzes the earthquake fissure types,distribution characteristics,nature and influence on transmission lines,and the engineering treatment measures.
