随着一系列新技术标准、新设计规范的实施和新建筑材料、新施工工艺的发展,原有部颁标准图在技术标准、荷载等级、材料、耐久性要求和施工工艺等方面已无法适应。原交通部专家委员会组织全国20多个勘察设计和科研单位编制了新的桥梁通用图。着重介绍了预应力混凝土T梁通用图编制过程的基本思路、计算方法和构造特点,以方便同行们在使用通用图时参考。
With a series of new technical standards, the implementation of new design codes and the development of new construction materials and new construction technologies, the original Ministry standard has failed to adapt to technical standards, load levels, materials, durability requirements and construction techniques . The original committee of experts of the Ministry of Communications organized more than 20 survey, design and scientific research units in the country to compile a new bridge general map. The basic ideas, calculation methods and structural features of the general drawing of prestressed concrete T-beams are emphatically introduced so as to facilitate the reference of the colleagues when using the general drawings.
