摘要
Abstract
Aiming at the complex stress state of double column variable cross-section curved concrete tower columns,this study takes the main bridge of Tarim Bridge as an example,analyze and compare the design process for the lower crossbeam setting scheme,optimization of the cable tower curve shape,and determination of the po-sition of the middle crossbeam.Research has shown that removing the lower crossbeam can reduce the number of times the cable tower is statically indeterminate,and has a significant impact on reducing the stress at the root of the tower column;different curve shapes affect the root size and overall stress of tower columns;the po-sition of the middle crossbeam has a significant impact on the deformation of the tower column in the trans-verse direction of the bridge.Taking into account factors such as stress state,displacement deformation,and aesthetic appearance,a reasonable form of cable tower structure is ultimately determined.关键词
