【摘要】 开敞式无围堰珊瑚砂岛礁吹填施工不修建临时围堰,直接吹填珊瑚砂,该工艺排水路径短,通过合理损失一部分粉细珊瑚砂,避免细颗粒累积,有效降低吹填体含泥量。通过在马尔代夫机场岛工程中应用无围堰珊瑚砂岛礁吹填施工技术,总结施工工艺流程、挖泥船选型原则、吹填工效控制措施、地基处理技术等。该工艺海上作业量少,安全环保,工程风险与成本低。更多还原

【Abstract】 Coral sand dredged filling construction with non-cofferdam reclamation method does not construct temporary cofferdam,but fills coral sand directly. The dredged path of this technology is short.By reasonably losing a part of fine coral sand,the accumulation of fine particles is avoided,and the mud content of dredger fill body is effectively reduced. The process has less offshore operation,safety,environmental friendly with low engineering risk and low cost.更多还原
