摘要
文章以解决高速公路改扩建项目中征地难、取土难为出发点,研发了一种新型的桩板式梁桥结构。该结构由工厂化预制的板和管桩组成,不需要征地和填土。文章进行了该新型结构的桩板连接、板与既有路基连接的设计,并用Midas Fea对结构进行全桥实体建模分析,给出了结构计算的结果。
In this article, a new type pile-plank bridge structure is developed aiming at the difficulties of land expropriation and filling in highway reconstruction and expansion projects. This frame structure system is composed of factory prefabrication plates and pipe plies, in which land expropriation and filling is not required. The design of pile-plate connection and the connection between plates and existing subgrade is introduced in this article. In addition, a whole bridge solid modeling analysis and calculation results are extracted from Midas Fea are provided in this article.
