中美公路桥梁设计规范对比研究

在承担南美洲一些国家桥梁工程设计中,一般都使用美国规范。因此,首先要对当事国使用的设计规范进行深入研究和分析,找出设计方法、设计参数取值、设计荷载及荷载组合等方面的不同;在相同跨径、截面及受力条件下,比较美国规范与我国规范钢筋混凝土梁的配筋计算结果,以此熟悉国外工程设计特点,了解与我国设计规范的不同点,提高设计质量,为其他国外工程设计提供参考,同时也为我国规范的改进和修订提供参考。

Comparative Study on Highway Bridge Design Standards between China and America

American standards are usually asked to be adopted in the bridge design in some South American countries.Firstly,in order to find out the differences existed in design method,parameter,load,load combination and other factors,the statutory design standards in the country-concerned should be studied and analyzed deeply.And then,the reinforcement result of reinforced concrete girder should be compared between using American standard and using Chinese standard under the same span,same cross-section and the same load.Based on these,the design features of foreign project can be known a great deal,the difference of design standards between China and foreign country can be acquainted,therefore the design quality can be promoted.Moreover,the comparative study can be referenced not only by the designers of other foreign projects,but also by those writers of Chinese standards when necessary to be revised.
