| Abstract: | 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. |
