抚顺石油一厂厂区裂陷变形特征及原因探讨

An Investigation on the Characteristics and Causes of Cracking and Subsiding Deformation in the Site of Fushun Petroleum Refinery No. 1

通过对厂区及其附近的裂陷变形调查,结合有关文献及资料,阐述了厂区地质构造及工程地质环境,指出厂区处于稳定的地台区。根据裂变特点,裂变形迹和强度,以及变形观测数据等,对厂区进行了裂变分带,探讨了规律性.与此同时,从活断层,地震等角度,论述了浑河断裂为非发震、非活动的断层.文章肯定了F_(1A)、F_1即为浑河断裂.进而利用区域调查及观测数据,说明了F_(1A)、F_1在厂区有活动则系诱发所致,不是自身构造运动的结果.最后综述了裂陷变形产生的原因。

Through geological survey of the cracking and subsiding deformation in the site of Fushun Petroleum Refinery No, 1 and analysis in combination with relevant literature and data, the geological structure and engineering geological environment of the site are expounded and the fact that the site is situated in the region of a stable platform is pointed out. Based on the characteritics, traces and intensity of cracking deformation, the data of deformation observation etc., zonation of cracking in this site is made and the regularities of cracking are explored. Meanwhile, from the viewpoint of active faults, earthquake activities etc., it is concluded that the Hun River fault is a nonseismic and inactive one. The paper confirms that F_(1A) and F_1 are the very Hun River fault. Furthermore, it is indicated on the basis of regional survey and observational results that the activities of F_(1A) and F_1 in the site, if any, should be induced by factors other than the tectonic movement of the faults their own. Finally, the causes leading to the occurrence of cracking and subsiding deformation are reviewed.
