九曲山半自锚式斜拉渡槽设计与施工

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

九曲山渡槽是江西省第一座斜拉式输水建筑物,渡槽采用双塔对称半自锚式塔墩固结支承体系。文中介绍了该渡槽结构体系、各组成部分型式及主要参数的选择国;内力计算的力学模型和计算结果;施工调索和施工中的控制等。

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.
