公路简支曲线桥梁的平面布设

在公路工程的设计中,不少桥梁受限于路线平面线形,位于曲线段,给桥梁的设计增加了较大的难度。简支梁桥因其结构简单、施工方便、对地基承载能力的要求不高的特点,广泛用于大中小桥上。该文结合工程实例,总结了公路曲线段简支梁桥的平面布设方法,简要介绍了各布设方法的特点及适用条件。

Plane Layout of Simply Supported Curved Bridge of Highway

Many bridges are limited by the plane alignment of line located at the curved section and increase the larger difficulty in the design of bridges in the highway projects.The simply supported beam bridge is widely used in various bridges because of its simple structure,convenient construction and low requirement of subgrade carrying capacity.The article sums up the plane layout method of simply supported beam bridge at the curved section of highway according to the engineering cases,and briefly introduces the characteristics and the suitable conditions of various layout methods.
