摘要
近几年,桥梁结构不断优化,斜拉和连续梁桥相互组合的桥梁——斜拉-连续协作体系桥作为一种新型结构逐渐出现,它兼有斜拉桥和连续梁桥的共同优势。为了体现出斜拉-连续梁协作体系的优越性,依托某斜拉-连续梁结构桥梁工程,通过MIDAS CIVIL有限元软件模拟对比斜拉桥、连续梁、桥斜拉-连续协作体系桥3种结构成桥阶段的静力特性数据,包括弯矩、变形等。实验数据表明,在同等跨度下,无论是工程量、成本还是受力情况,斜拉-连续协作体系桥都有一定的优越性,协作体系的挠度值位于斜拉桥和连续梁桥之间,表明协作体系是位于柔性和刚性之间的一种比较理想的新型桥梁结构。
Based on a cable-stayed continuous beam structure bridge project,this paper simulates and compares the static characteristic data of three different structures such as cable-stayed bridge,cable-stayed continuous cooperation system and continuous beamby using MIDAS CIVIL finite element software.The experimental data show that under the same span,the cable-stayed continuous cooperation system has certain advantages,regardless of engineering quantity,economy and stress angle.The deflection value of the collaboration system is located between the cable-stayed bridge and the continuous beam bridge,indicating that the collaboration system is an ideal new bridge structure between flexibility and rigidity.
