摘要
总结现有的海岸防护工程方法及效果,提出PEM透水管新型养滩护沙技术,为沙滩整治和养护工程引入一种绿色、低碳的新技术。通过二维波浪物理模型试验,在不同波浪条件下对PEM透水管养滩护沙效果进行分析研究,主要讨论了波高及透水管间距对养滩效果的影响。试验研究表明,波高对透水管养滩护沙效果影响较为明显,在波高H=1.5 m、2.0 m和3.0 m时透水管养滩效果较为明显,波高H=4.0 m时效果较差;合理的透水管间距也可以提高透水管养滩护沙效果。
The existing coastal protection engineering methods and effects were summarized,a new beach and sand protection technology with PEM permeable pipe was proposed,which introduced a green and low-carbon technology for beach regulation and maintenance.Based on two-dimensional wave physical model test,the effect of PEM permeable pipe on beach and sand protection was analyzed under different wave conditions.The influence of wave height and permeable pipe spacing on beach maintenance effect was mainly discussed.The results show that the effect of wave height on beach and sand protection by permeable pipe is obvious,when the wave height is 1.5 m,2.0 m and 3.0 m,the effect is obvious,while the effect is poor when the wave height is 4.0 m.Reasonable spacing of permeable pipes can also improve the sand protection effect of permeable pipes.
