摘　　要：人工沙坝喂养海滩是一种新型的治理海滩侵蚀方法。本文通过对人工沙坝消减波浪的机理出发,推导出了沙坝消减波浪的理论公式。为了进一步验证理论公式和人工沙坝养护海滩的效果,以北戴河某海滩为原型,进行了试验室二维断面模型试验。研究结果表明:在水深较小时,推导得到的波浪变化理论公式有效性较好;采用人工沙坝方法养护海滩效果明显。Beach nourishment by artificial sand bar was a new method of beach erosion controlling. The paper deduced the theoretical formula of the wave propagation and deformation on sand bar, based on the mechanism of weakening wave by artificial sand bar. In order to further verified the theoretical formula and the effect of artificial sand bar to the maintenance beach, the paper carried out the 2-d experiment based on a beach in Beidaihe.The results show that the theoretical formula of wave variation is better in shallow water, and the effect of beach nourishment by artificial sand bar method is obvious.
