中文摘要：
基于波浪水槽实验,对孤立波作用下沿海公路局部冲刷开展实验研究。实验采用1/10与1/20组合坡模拟海岸地形,对岸滩进行逐个多次波浪作用,用地形仪对作用后地形进行测量。通过改变路基在冲刷槽的绝对位置和相对位置,探讨路基位置因素对局部冲刷影响。实验结果表明：孤立波作用下沿海路基向海侧出现明显冲坑,冲刷深度随波浪作用个数增加,最后达到平衡。路基位置是路基局部冲刷主要因素,随着路基位置远离海岸线,路基向海侧冲刷深度呈减小趋势。
英文摘要：
A set of 2D laboratory experiments on solitary wave scour at a coastal road situated on a sandy beach were performed to investigate the scour around the coastal structure. The initial 1/10-1/：20 composite beach slope was exposed to the solitary waves actions. The changes of beach profile were measured by terrain instrument. By changing the embankment scour＇s absolute position and relative position, the roadbed location influence on the local scour is explored. The result shows that there is an obvious scour affected by solitary waves around the seaside of the coastal road, and that with increase of wave number, scour depth finally gets balanced. It also shows that the coastal road location is the main reason for the local scour and that the sea side scour depth presents a decreasing trend.
