摘要
通过对滨海地区第四纪地质调查等资料整理分析,以工程勘察钻孔资料为验证手段,确定了滨海地区晚更新世末期至全新世中期部分深切古河道的空间分布,并对其历史成因进行了推测;结合深切古河道的特殊工程地质、水文地质特性,对其在工程建设中产生的不利影响进行了分析。
Based on the analysis of the Quaternary geological survey data in coastal areas,using the drilling data of engineering investigation as a means of verification,we have ascertained the spatial distribution of some deep erosional paleochannel in the late Pleistocene to mid Holocene in coastal areas,and speculated on itshistorical origin;Combined with the special engineering geological characteristics and hydrogeological characteristics of the deep erosional paleochannel,we analyzed the adverse effects on the engineering construction.
