摘要
应用多种途径对抚顺目标区的浅层反射横波活断层勘探资料进行的解释与分析,证实了浑河断裂总体上为北倾、逆断的性质,且只是在采空区表现为新的活动段,本身不是由构造活动原因引起的活动断裂。在第四系埋深浅的地区,反射横波法是具有较强抗干扰能力的活断层探测技术,可靠程度及解释精度均较高。本文为抚顺市活断层的地震危险性评价工作奠定了基础。
On the basis of the multi -way interpretation and analysis on the shallow seismic S-wave reflection prospecting of active fault in Fushun, it has been proved that the nature of Hunhe Fault shows north trend and converse. And it＇ s not an active fault induced by tectonic movement, but a new active segment in those empty regions exploited. The shallow seismic S-wave reflection prospecting is a kind of method with strong resistance to disturbance, high resolving power, which rather fit in the areas shallow quaternary strata buried.
