Hydroelectric power house metal spiral case periphery structure is below the hydraulic turbine layer inside the two phases concrete scopes the reinforing steel concrete structure,being a space structure that the wholeness is very strong,his bodily form is complicated.Except the available three dimension finite element methods are analysed his space stress state,still there is not the available internal force of accurate method with the calculation periphery structure.Generally still use frame mechanics law calculation internal force on plane in the periphery physical design at present.Some huge currents capacity power stations are big owing to the turning wheel diameter,and spiral case is intake,and the pipe diameter is big,and the seat ring size is small,and even the knot is unreliable to a seat ring place concrete.The as if will be looded around for one not moving and cut with scissors by the seat,and the outer periphery solidifies calculation,and to join in marriage the muscle inadequate probably to the solid end of periphery outside the spiral case.It is fixed admittedly that this text is put forward according to the periphery outside the elasticity thin board theory,and the annular board wall of interior periphery freedom counts.
