海岸工程中传统的人工块体护面结构下均设有砌石垫层,但上海地区石料缺乏、块石材料与砌石施工质量控制较难。南汇东滩促淤工程关键技术示范研究中,针对上述问题对护面结构进行了改进研究,本文以小风浪区螺母块体护坡为例,研究提出了杯型螺母块体护坡新型结构,使传统螺母块体与块石垫层的两者功能合二为一,并在崇明北沿三期工程护面结构中得到成功应用,实施效果良好。
In the coastal engineering, masonry mats are arranged under the traditional artificial block hull structure, but the lack of stone materials in Shanghai and the hard quality control of block stone materials and masonry construction. In the research on the key technologies of silt-silting project in Nanhui District, aiming at the above problems, the research on the structure of the protection surface is improved. Taking the nut block slope protection in small waves and waves as an example, a new type of cup- Both the function of the nut block and the stone cushion layer are combined into one, and the application has been successfully applied in the construction of the sheathing of the third phase project of Chongming North along the line. The implementation effect is good.
