Design and Construction of Jiuqushan partially Self-anchored Cable-stayed Aqueduct

Jiu-qu-Shan aquedut is the first calbe-stayed conveyaace structure in Jiangxi province. It uses a suppoting system with two symmetrical towers, in which the cables are partially self-anchored and the towers are fixed at the piers. This paper presents the choice of the structure system and the component types as well as main parameters, the mechanical model of the ccalculation of internal forces and its result, the adjustment of cable force and the control of construction etc.
