连云港西大堤工程后人工海湾内回淤强度的测算分析

本文重点研究了连云港西大堤工程后人工海湾内的回淤状况,得出以下结论：西大堤的封堵使人工海湾内的水动力和泥沙运动产生了明显的变化。但这只是工程后的局部调整,不会造成严重的淤积。由于湾内泥沙供应量的减少,连云港仍将维持冲淤相对平衡的状态。并且,本文以实测资料为依据,对两类主要的回淤预报公式进行了分析评价,证明了这两类公式的合理性和可靠性。

Sedimentation intensity of the artificial bay in Lianyungang after the construction of West Breakwater

In this paper, the sedimentation of Lianyungang Harbor basin after the construction of West Breakwater is studied with the key conclusion that the construction of West Breakwater changes greatly the marine dynamic force and sedimentation. However, the change will not lead to severe deposition. With the decrease of sediment supply, the sedimentation and erosion of Lianyungang Harbor will keep balanced. On this basis, two kinds of models for the forecasting of sedimentation in Lianyungang Harbor are appraised in this paper. It is clear that they are reasonable and dependable.
