摘    要:在沙质海岸上修建导流堤、丁坝等会引起局部海域水沙动力条件的改变和海床冲淤调整,因此准确预测沿岸输沙率是海岸工程建设前进行优化设计的基础条件之一.首先构建了刻画高强度推移质输沙过程中固-液混合体运动的理论模型,通过寻求模型的特解并推导成1D沿岸输沙率公式.该公式适宜计算强浪作用下的推移质输沙率,已得到了大型波浪水槽、往复流水道和海滩现场实测输沙率资料的良好验证.通过与物理模型试验实测输沙量结果的比较,进一步表明该公式能够较好地预测沙质海岸在寒潮大风浪(或台风浪)作用下的高强度输沙量(骤淤量).

关 键 词:沙质海岸  强浪  沿岸输沙率  理论模型  物理模型试验

Abstract:The construction of breakwaters or groins on sandy coasts could change the local flow field,leading to adjustment of beach erosion and accretion.It is thus important to predict the longshore sand transport volume for optimum engineering design.By treating the movement of solid-water mixture as continua during the intense transport of bedload sediments,the present study builds a mathematical model and then seeks its special solution,which is subsequently developed into a 1D longshore sand transport rate form...
Keywords:sandy coast  strong wave  longshore transport rate  theoretical model  physical-model experiment
