| 摘 要： | 为得到横向拓宽空心板桥基础沉降的次内力影响,本文以某一级公路扩建工程为背景,建立了三维实体有限元模型,并考虑沉降计算模式及徐变的影响,对拼宽部位结构的次内力及适宜构造进行分析探讨。基于本例计算,作者推荐空心板简支梁桥的拓宽拼接构造宽度为0.5m左右。

| Abstract: | The purpose of this article is to obtain the effect of the secondary internal forces induced by differential settlement article is based on a highway expansion of a hollow project. By slab simple support bridge. The establishing a three-dimensional solid finite element model and considering the effect, of the computing model and the effect of the creep, the article analyzed the secondary internal force in the widening part of the bridge and investigated the suitable structure. Based on the calculation of this case, we recommended a width around 0.5m for the widening splicing structure of a hollow slab simple supported beam bridge. |
