摘要
潮汐河口上超大型龙口保护与截流难度极高。围绕软土地基、高流速往复流和便于大型船机作业等特点和要求,结合青草沙大型水库实践,采用一系列研究方法,创新提出了以超强软体排为特征的龙口护底和以钢框笼内抛石为特征的合龙工艺和结构,成功经历了实践的考验。
Both the protection and closure of extra-large closure gap of tidal estuary are quite difficult. Based on the construction practice of a large reservoir--Qingcaosha Reservoir, the construction methods of the bed protection for the closure featured with the super-strengthened flexible geotextile mattress and the closuring technology and structure featured with steel cage filled with riprap are innovatively put forward on the basis of a series of studies concerned for the soft soil foundation and reversing current therein under the requirement to be convenient for the constructions of large ships and machineries ; which have been successfully applied to the project.
