| 摘 要： | 对于中等跨径的梁式桥,通过对普通连续梁桥、V型墩连续梁桥、斜腿刚构桥三种桥型的受力特性和施工方法的比较,分析出它们截面及预应力配筋的差异。进而得出在一般条件下应优先选用斜腿刚构桥。这种桥型在受力、经济等控制因素上均具有可比性。

| Abstract: | For girder bridges with medium spans, comparison is made in the stress features and construction methods between the three types of bridge, i.e. the common continuous girder bridge, the continuous girder bridge on V-formed piers and the slant legged rigid frame bridge. Analysis shows that the difference lies in their section and prestressing reinforcement. A conclusion is then drawn that the slant legged rigid frame type shall generally be adopted, which is better in force bearing, more economic, etc. |
