摘要
预应力小箱梁桥以其自重较轻、梁高较小以及出色的抗扭能力,在中小跨径桥梁中得到了广泛的应用。本文以下方有多条隧道穿过的某宽幅小箱梁桥为工程背景,详细介绍了其不等跨布桩设计,并运用Midas Civil进行有限元分析计算,验证了本桥设计方案的合理性,为今后类似的桥梁设计提供参考。
Prestressed small box girder bridge has been widely used in small and medium span bridges beeause of its light weight, small beam height and exeellent torsion resistanee. A wide box girder bridge aeross a subway tunnel taken as an example, this paper introduces the process baekground, and the design of unequally distributed span piles is explained. The Midas Civil is used to earry out the ealeula- tion and analysis of the upper and lower parts, and the rationality of this bridge design is verified.
