MOVEMENTS OF SEDIMENTS IN THE QINGDAO CITY COAST
-
摘要: 根据2002-2005年在研究区所获取的237个表层沉积物样品的粒度分析、浅地层剖面和多波束测量以及水动力等有关资料,对青岛前海的动力作用和物质运移进行了讨论,结果表明:在特定的动力作用下,青岛前海可区分出5种沉积类型;从胶州湾口到东部的拦门沙坝外侧,为一套以退潮流为主体的泛平原沉积体;潮流侧向运移结果形成潮道两侧的(南北)沙脊;沿岸各海湾海滩中部和沿岸波基面附近则是波浪作用的含砾砂质沉积体。本区的动力作用主要是潮流和波浪,潮流主要对纵向和侧向滚动旋转的物质运移起作用,波浪和局部沿岸流则对沿岸各海湾沙滩提供物质并对沉积物分选起作用。Abstract: In order to investigate the movement of sediments in the Qingdao City coast, the authors discuss the dynamic effect and material movement in this area according to the data of granularity, shallow seismic section, multiple-beam measurement and hydrodynamic process showed by 237 surface sediment samples collected during 2002-2005. The results indicate that under the special dynamical effect there are five types of sediments in the study area, which are flood-plain sedimentary system the main part of which is of ebb origin from the mouth of the Jiaozhou Bay eastwards to the outside of the barrier bar, sand ridges resulting from lateral movements of tidal currents on the sides of the tidal channel, and wave-induced gravel-bearing sands in the middle of the bay beaches and at the nearshore wave bases. The dynamical functions are mainly tides and waves in this area. Tidal currents have an effect on the longitudinal and lateral rolling rotation of sediments while waves play an important role in the material supplement for the beaches and the sorting of sediments.
