天津滨海新区南部海岸带晚第四纪沉积物工程地质特性研究
Engineering geological characteristics of Late Quaternary sediments in the southern coastal area of Tianjin Binhai New Area
摘要
Abstract
Tianjin Binhai New Area is located in the west muddy coastal area of Bohai Bay. It formed marine sedi-ment and terrigenous sediments alternating strata since the middle-late Pleistocene. Based on detail analysis of the sedimentology, chronology and physical and mechanical parameters in more than 30 boreholes, this paper dis-cussed the sediment physical and mechanical properties of different sedimentary facies since the middle-late Pleistocene in Southern coastal area of Tianjin Binhai New Area, and the engineering geological characteristics were evaluated. The results showed that since the middle-late Pleistocene in study area, continental strata is dense and hard plastic; moisture content is low; void ratio is low; compression is low; and the bearing capacity is high. The engineering geological characteristics of silt or silty sand section in marine strata is similar with continental strata, but cohesive soil section in marine strata; moisture content is high; void ratio is high; compression is high;and bearing capacity is low.关键词
