本文用物理模型方法对沙质海岸上港工建筑物下游海岸冲刷形态进行了实验研究。实验中以天然海滩细沙作为模型沙。经过大量试验,取得了描述下游冲刷形态的一些特征参数试验数据,以及这些特征参数随动力因素的综合效应——输沙量的变化规律。对冲刷形态的逐年变化特性也进行了探讨。在一定试验条下获得的试验成果,可供类似工程项目的选址、规划和可行性研究阶段参考应用。
In this paper, the physical model method is used to study the coastal erosion pattern of the downstream structures on the sandy coast. In the experiment, the fine sand of natural beach was used as model sand. After a large number of tests, some experimental data describing the characteristics of downstream scouring conditions and the comprehensive effects of these factors on the sediment discharge have been obtained. The change characteristics of scouring patterns from year to year are also discussed. The test results obtained under certain test strips can be used for reference in the siting, planning and feasibility studies of similar projects.
