摘要
2009年和2013年对北戴河中海滩二浴场进行了一期治理工程和二期治理工程,通过对2次养滩前后的监测剖面数据的研究和2次养滩工程效果对比分析得出:①2009年的一期治理工程后,海滩经过了近4年的自然演化,至2013年3月,海滩侵蚀后退较大,必需开展二期的整治工程;②2次工程都为成功的养滩实例,从养滩后的3个月以及6个月的剩余填沙体积(一期:91.9%、77.5%;二期:95.9%、86.8%)对比可以看出,二期整治工程效果更加理想。为进一步查看二期工程效果,探索影响养滩效果的因素,需继续进行工程后的养滩监测。
Two projects of beach nourishment were carried out respectively in 2009 and 2013 at the second swimming pool of the Middle Beach of the Beidehe Beach. Comparison and analysis of monitoring data after the two projects suggest that： （1） after natural evolution for four years after the first nourishment project in 2009, up to March 2013, erosion was very strong there. The swimming beach eagerly needs a restoration project to maintain it from erosion; （2）Both the two projects are successful cases of beach nourishment. The contrast of remaining filling sand volume for 3 months and 6 months after nourishment shows that the 2^nd beach nourishment project is more successful. In order to assess the effectiveness of the project and to explore the factors which influence beach nourishment, continuous monitoring of the beach is recommended.
