我国《公路桥涵设计规范》(以下简称《桥规》)总结了建国以来公路桥涵设计和施工方面的丰富经验,它不但提供了比旧《公路设计准则》更加成熟的计算原理,而且还提供了一些符合我国桥梁生产实际的工程数据,它对我国公路桥涵设计起着促进和指导作用。但是,生产建设和人们的认识在不断地发展,因而,对《桥规》中的某些问题,进行研究讨论,是必要的、有益的。本
China’s “Code for Design of Highway Bridges and Culverts” (hereinafter referred to as “Bridge Regulations”) summarizes the rich experience in the design and construction of highway bridges and culverts since the founding of the People’s Republic of China. It not only provides a more mature calculation principle than the old Highway Design Guidelines but also provides Some of the engineering data in line with the actual production of bridges in our country, it plays a guiding and promoting role in the design of highway bridges and culverts in China. However, production and people’s awareness are constantly evolving. Therefore, it is necessary and beneficial to study and discuss some issues in the “bridge rules.” this
