摘要
本文针对某条高速公路,对高架桥梁常用的下部结构型式进行了介绍和比选,并对下部结构设计过程中的主要计算内容(桩基、承台、立柱、盖梁)作了详细论述。文中特别讲解了如何对倒T盖梁进行施工阶段抗扭验算和参照美国规范进行牛腿验算。
Taken an expressway as an example, some common substructures and the comparisons between them are introduced. Then it is presented the detailed calculations in the design of substructure components including piles, pile caps, upright columns and copings. Finally the checking computations on the torsion resistance of inverted T type copings in construction periods and on corbels according to American codes are explained especially.
