| 摘 要： | 浑河断裂带是深大断裂-郯庐断裂的北延分支,横贯抚顺市区,在断裂带之上及其两侧建有诸多大型工矿企业及民用建筑,断裂带的稳定与否关系到抚顺市的城市安全。近期,浑河断裂带抚顺市区段的个别次级断裂发生活动,并已造成严重的城市建筑破坏。局部断裂活动的成因,为城市决策者所关注。本文利用抚顺市城市平面控制网相隔17a的两期GPS测量数据,应用大地形变分析的理论方法,对浑河断裂带抚顺市区段的稳定性进行了定量分析,得出结论:浑河断裂带抚顺市区段的宏观地质构造在此期间活动性不明显。

| Abstract: | Hunhe fault zone is part of the northern extension of Tanlu fault zone,coming across the city of Fushun.Therefore its stability is crucial to the safety of Fushun,since many big factories,mining and dwelling house are built above and along the fault zone.Recently,activities of some secondary fault zone in Hun River fault zone have been discovered,in particular,in Fushun urban district,causing severe damage to city construction.Results of partial fault activity were attented by decision-makers of the city.This paper uses two sets of GPS survey datum of City planar control network of Fushun,which were collected with the interval of 17a.,and with the theoretical method of crustal deformation analysis,the quantitative analysis of the stability of Hunhe fault zone in Fushun urban district is made,and the conclusion is that the whole geologic structure activities of Hunhe fault zone in Fushun urban is inapparent in this period. |
