弯、坡、斜连续刚构桥菱形挂篮设计研究

A Study of the Design of the Prismatic-Shaped Hanging Basket for the Construction of Curved,Sloped,Oblique Continuous Rigid-Structured Bridges

针对高速公路(77+140+77)m三向预应力混凝土连续刚构桥的工程实际情况,在介绍构造和原理的基础上,对弯、坡、斜连续刚构桥菱形挂篮进行了详细的结构设计,并利用通用计算程序作了受力检算分析,保证了该桥施工进度和安全,可供类似工程参考借鉴。

With the practical construction of the 3-direction, （77 ＋ 140＋ 77） m, continuous rigid-structured pre-stressed concrete bridge of the expressway as a practical example,and upon the basis of introducing the structural composition and principles of the prismatic-shaped hanging baskets,the structural design of the prismatic-shaped hanging basket for curved,sloped, oblique continuous rigid -structured bridges is performed in detail in the paper, with the universal computation programs adopted for checking to ensure the scheduled construction progress and safety of the bridge. The paper may serve as a useful reference for other similar projects.
