Abstract

A finite element computer code, ANSYS 5.2, was employed to study the deformation
of a high-pressure sluice gate.  The sluice gate was installed at the end of
water-releasing tunnel of Nan-Hwa reservoir, Nan-Hwa, Taiwan, R.O.C.
Different kinds of water pressure loading orthogonal acting upon the upstream
side of gate leaf, such as: 3.5 kg/cm2(equal to 145 m water height),
5.5 kg/cm2(equal to 165 m water height), 7.5 kg/cm2(equal to 185 m water height),
9.5 kg/cm2(equal to 205 m water height), 11.5 kg/cm2(equal to 225 m water
height), and 13.5 kg/cm2(equal to 245 m water height) were respectively used to
predict the deformation of the  sluice  gate. The effect of constrain,
the boundary conditions of bearing plate of sluice gate, on the sluice gate
deformation was investigated, too.
