道路与桥梁工程概论论文 道路与桥梁工程概论论文 ——浅谈斜拉桥的差不多概况及进展前景 ——浅谈斜拉桥的差不多概况及进展前景 摘要:斜拉桥是将主梁用许多拉索直截了当拉在桥塔上的一种桥梁是一种由塔、 摘要:斜拉桥是将主梁用许多拉索直截了当拉在桥塔上的一种桥梁是一种由塔、 梁、索三种差不多构件组成的组合桥梁结构体系,可看作是拉索代替支墩的多跨 弹 梁、索三种差不多构件组成的组合桥梁结构体系,可看作是拉索代替支墩的多跨 弹 性支承连续梁。其可使梁体内弯矩减小, 降低建筑高度,减轻了结构重量,节 约了材 性支承连续梁。其可使梁体内弯矩减小, 降低建筑高度,减轻了结构重量,节 约了材 料。斜拉桥由索塔、主梁、斜拉索组成。斜拉桥在目前所有桥型中具有鲜 亮的特点 料。斜拉桥由索塔、主梁、斜拉索组成。斜拉桥在目前所有桥型中具有鲜 亮的特点 和优势。在此浅述有关斜拉桥的进展历程和建筑技术要点,以及斜拉桥 在世界桥梁 和优势。在此浅述有关斜拉桥的进展历程和建筑技术要点,以及斜拉桥 在世界桥梁 进展史上的地位和进展前景。 进展史上的地位和进展前景。 关键字:跨径结构体系构造建筑美学 关键字:跨径结构体系构造建筑美学 Abstract With many girder cable-stayed bridge is will draw directly lasso in bridge tower Abstract With many girder cable-stayed bridge is will draw directly lasso in bridge tower : : bridge, is a kind of by a tower, beams, cable three basic components combination bridge bridge, is a kind of by a tower, beams, cable three basic components combination bridge structure system, can be considered a lasso more instead of a pier across the elastic structure system, can be considered a lasso more instead of a pier across the elastic supporting continuous beam. It can make the beam is reduced, reduce body bending supporting continuous beam. It can make the beam is reduced, reduce body bending moment the height and reduce the weight, sa ing material struct urCeable-stayed bridge moment the height and reduce the weight, sa ing material struct urCeable-stayed bridge ・ ・ by cable tower, girders, composed stay-cables Cable-stayed bridge in the present in all by cable tower, girders, composed stay-cables Cable-stayed bridge in the present in all
