摘要

摘要: 用数值模型方法计算了渤海海峡区潮流引起的最大和平均底应力,以及相应的活动层厚度的空间分布,并根据沉积物参数计算了沉积物临界起动切应力。计算结果的分析表明 :(1)最大潮流底应力和沉积物临界起动切应力的关系与底质分布之间存在着明显的对应,最大潮流底应力大于临界起动切应力的地方,分布着粗颗粒沉积物,若前者小于后者,对应的是细颗粒沉积物,若两者近于相等,则对应着较细颗粒的沉积物;(2 )在山东半岛北部近岸和渤海海峡的东北角,最大潮流底应力小于或接近于临界起动切应力的量值,而对应的沉积物是粉砂和砂,这一例外可能是由于残留沉积的出露,这一假说需要根据全新世海面上升历史、古水动力环境模拟、渤海海峡沉积环境演化等方面的研究来验证;(3)活动层厚度的分布规律与海底沉积物的分布存在着相关性 :即活动层厚度越大,对应的海底沉积物越粗;活动层厚度越小,对应的沉积物越细。

Abstract: A 2-D ho rizontal numerical model is used to simulate maximum and mean tidally-induce near-bed shear stresses and the corresponding mobile layer thicknesses in the Bohai Strai t region.At the same t ime, the cri tical near-bed shear st ress was calculated using the g rain size parameters.An analysis of the results show s that :(1)the seabed sediment types are related to the dif ference between the t idally-induced shear stress and the cri tical shear stress (a larger difference is associated w ith a coarser bed material);(2)in some places (e.g.the northeastern part of the Strait and the near-sho re areas of the northern Shandong Peninsula)the tidally-induced shear st ress is smaller than the critical shear st ress, but the seabed sediment is relatively coarse, indicating that the sediment may represent relict materials (this hypothesis should be tested by the result s f rom future investig at ions into the Holocene sea level changes, paleo-hydrody namic conditions and the evolution of the sedimentary environment);and (3)a good correlation betw een the mobile layer thickness and the sediment type exists, i.e., a large mobile layer thickness is associated with relatively coarse sediments, and a small thickness is associated with fine-grained sediments.
