Overturning calculation and structural analysis of floating gate
It is proposed to decompose the rotary sinking motion of floating gate during water filling into two indepen-dent motions of sinking and rotation.The calculation formula of the rotation center of traditional constant cross-sec-tion floating bulkhead gate during water filling is deduced by analytical method.Based on the calculation formula of rotation center,the overturning processes of the constant section floating gate and variable section floating gate are analyzed,and its draft,required counterweight and stability are compared and analyzed.It is concluded that the structural form of variable section floating gate combined with gate bottom counterweight has higher stability and lower requirements for water depth in the overturning process.
