摘　　要：为研究在采煤沉陷水域进行漂浮建造的方法,运用三维数字化模拟,建立漂浮建造的规划布局和形态模型,提出漂浮建造方案:漂浮模块由上部结构、漂浮基座和系泊结构组成,单元式模块按需组合即可构成有机体系,并对此进行结构设计及计算方法研究.结果表明:上部结构和漂浮基座采用钢筋混凝土框架结构时,二者正投影面积比为1∶3,基座平面型式为正方形,由顶板、侧板和底板围合组成.采用桩基或者牵拉方式系泊固定:桩基系泊时,设置截面1.0m×1.0m和长度25.2m的钢筋混凝土抵抗柱;牵拉系泊时,在4个不同方向设置直径45mm的伸缩钢缆牵拉漂浮模块.In order to study the construction method of the floating construction in mining subsidence water area, the planning layout and spatial model of the construction were designed with the aid of three-dimensional digital simulation. In the proposed design scheme, the floating module consist of su- perstructure, floating foundation and mooring structures; the unit module were assembled into the floating organic system as required. The related structure design and calculation method were investi- gated. The results show that the ratio of orthographic projection area is 1 to 3 when the reinforced concrete frame structure is adopted in the superstructure and the floating foundation. The plane of floating foundation is square, which is made up of the top, side and bottom plates. The pile founda- tion and traction mooring structures are designed to fix the floating modules to the underwater pile foundation. For the former mooring structure, the square resistance column is 25.2 m long and 1 m on a side, and four stretchable steel cables with a diameter of 45 mm are designed to fix the floating mod- ule at four different directions.
