| Abstract: | The operation characteristic of miter gate and the prestress method under different back tie rod arrangements are discussed in this paper. The modulation method of back tie rod prestress is analyzed in terms of the individual size of the gate and the structure along with the change of prestress distribution and the different relationship between back tie rod prestress and the gate shape. The new method has obvious technic and economic benefit. |
