某断裂活动性鉴定及其工程意义

拟建某社区住宅楼工程场地存在一条北西向断裂,定名为F断裂。通过地质地貌调查、探槽开挖、断裂断错地层分析等工作,鉴定了F断裂的活动性,评价了断裂对社区住宅楼的工程影响,提出了工程设计和断裂避让的处理措施。本项研究是断裂的活动性鉴定在工程建设具体应用的实例,对其它相关工程断裂活动性鉴定及其工程影响评价具有借鉴意义。

IDENTIFICATION OF A CERTAIN ACTIVITY AGE OF THE FAULT AND ITS ENGINEERING SIGNIFICANCE

There is a fault ranged from the north to the west which called F fault in one community residential buildings of proposed projects. Through the geological survey, exploratory trench excavation, analysis of the fault dislocation formation, we identified the activity of F fault,evaluated the project effect on community residential buildings, and put forward some measures to handle the engineering design and avoiding faults. The study is a model of fault activity which are applied on project construction,and it also has some reference significance to identify other related fault activity and its project assessment.
