摘要
综述槽形梁的结构特征、分类情况及在桥梁中的应用发展状况。介绍国内外典型槽形梁桥的断面形式、跨度、墩台形式等设计详情,对比相关设计参数,罗列了常用的槽形梁施工方法。最后,对槽形梁在应用中存在的问题和研究发展趋势提出几点看法。
This paper summarizes the structure characteristics, classification, and the development situation of trough girders used in bridges. The design details of several typical trough girder bridges at home and abroad, such as the cross-section type, span length, pier and abutment type and so forth, are also introduced. Moreover, relevant design parameters are compared with each other, and then the commonly-used construction methods of trough girder are listed. Finally, for the existing problems in the application of trough girder as well as for the further study and development direction, some viewpoints are suggested here.
