摘要
Abstract
There are many problems in box-girder bridge at construction stage, especially at closure segments, such as bursting cracks in bottom slab, longitudinal cracks in the bottom slab and tearing in the bottom slab. Taking a bridge as the engineering background, the causes leading to the cracks are analyzed using the finite element software. Some parameters are also analyzed to research those cracks, and corresponding improvements for the design and construction of this type of bridge are proposed.关键词
