Design of Curved Cable Tower Foundation for Single Tower Cable-stayed Bridge

LIUBohai，XIEQi

【Abstract】：Aiming at thecomplex stressproblemofthecurved cable tower foundation，takingthe main bridgeof Tarim Bridge as an example，considers some factors such as geological conditions，structural force，reasonable economy，convenience in building and soonto determine the reasonable scheme of the pylon foundation after multiple rounds of comparisonand selection.It also analysis the effect of the stiffness deformation of the pile cap onthe group-piles foundation byusing the finite element model.At the same time，the outcome helps to optimize the scheme.The final scheme meets the requirement of structural stress with different effects combination.

[Keywords】：cable stayed bridge with single tower；arc shape of the tower column；group-piles foundatior

大跨度斜拉橋、懸索橋基礎(chǔ)的受力通常比普通梁橋更加復雜，其基礎(chǔ)布置型式與索塔的造型特點有很大關(guān)系，設(shè)計中需要考慮的因素較多，設(shè)計過程繁瑣。（剩余4729字）
