浑河断裂活动性对抚顺市区地裂缝的影响

摘要

辽宁抚顺是一个以燃料工业为主的综合性工业城市,素有煤都之称,由于长期的煤矿开采,滑坡、地面沉陷、塌陷、地裂缝、矿震等地质灾害频繁发生,其中地裂缝对市区已建城区建构筑物的直接破坏比较严重,地裂缝是指与地震无直接关系的地面或房屋等建筑物开裂现象.在市区内,典型的地段有抚顺西露天采场北帮和市区东部的东林-榆林地区,位于其上的居民区和工厂企业大部分被搬迁.由于浑河断裂在抚顺市区通过,规模较大的地裂缝均位于主干断裂及次级断裂之上,因此对浑河断裂活动性的讨论尤为重要,本文重点论述了在煤田开采引发地质灾害的基础上,断裂本身的活动性对地裂缝的影响.%Because of long term coal mining, geological disasters occur frequently in Fushun. The architectural structures of urban constructions have been greatly damaged by ground fissures. The Hun river fracture is cross Fushun city, which caused main ground fissures all located in the main fracture and secondary fracture. So it is important to discuss the activity of Hun river fracture. In this paper, we mainly discussed the influence of the fracture activity on the cracks and the cause of geological disasters in coal mining area.
