上海石化总厂化工物料码头对附近水下地形变化的影响

分析了上海石化总厂化工物料码头周围水下地形工程前后的变化。指出在淤泥质岸段,由于沿岸工程的影响,造成工程附近水域动力环境的改变,水下地形随之作出相应的调整。特别在淤泥质岸段附近流急、含沙量高的水域中构筑沿岸工程,工程的水流下方一侧,水流减缓,水流挟沙能力大大减弱,出现明显的局部淤浅地形,为提高工程效益,对各工程之间的相互影响,应予以重视。

THE INFLUENCE OF THE CHEMICAL WHARF OF SHANGHAI PETROCHEMICAL COMPLEX ON SUBMERGED TOPOGRAPHY CHANGES IN NEARBY REGIONS

The changes of submerged topography around the Chemical Wharf of Shanghai Petrochemical Complex due to the construction of the Wharf project are analyzed For a stretch of muddy coast, due to the influence of coastal engineering, the dynamical environment of adjacent waters will be changed, and corresponding adju stments will be consequently made in the submerged topography. Especially, if some coastal projects are constructed in a region with strong currents and high sand content, the downsteam current of the projects will slow down, and its sand carrying capacity will decrease remarkably, causing some obvious partial shoaling to appear. Therefore, in order to raise the benefit of a project, the influence among projects should be considered.
