摘要
以北戴河老虎石浴场为例,运用剖面分析模型,对海滩养护后海滩剖面的变化进行长期监测研究,分析海滩人工养护后的演化趋势。研究结果表明,养滩后3个月侵蚀最为严重,3个月后海滩侵蚀明显减小,14个月后的侵淤近乎平衡,仅有少量侵蚀。填沙养护1年半后滩肩宽度平均增加约16.2 m,填沙保存62.5%,养滩效果良好。
Taking Laohushi Beach of Beidaihe as an example, carried out long-term monitoring and studies on the changing trends of beach profiles with a profile analysis model, and analyzed the evolution trends of beach after artificial nourishment project. The research results showed that the beach was obviously eroded in the first three months and then the erosion rate obviously reduced three months after beach nourishment project, and the beach almost achieved a dynamic equilibrium between eroding and depositing fourteen months after artificial nourishment project. A year and a half after artificial nourishment project, the width of beach berm was increased by 16.2 meters on average compared with that before artificial nourishment project, and 62.5 percent nourishment sand was preserved. These results above indicated that the artificial nourishment project has obtained good effect and successful experience.
