| 摘 要： | 以混凝土连续宽箱梁桥为对象,探讨了腹板间距、腹板与顶底板刚度比等参数变化情况下预应力横梁的内力分布规律与特征,并提出了相应的计算方法,研究结果表明,宽箱梁桥恒载大部分由腹板传递给横梁,小部分由顶底板传递,分配比例与腹板、顶底板刚度比有关。

| Abstract: | Taking the example of suiting concrete wide trunk bridge,it discusses the pre-stress distributing regularity and features when the parameters change in belly-board distance,belly-board and bottom board rigidity.It also advances some relative calculating methods.The result shows,most parts of laden wide trunk bridge are transformed to crossbeam by belly-board,the minority is transformed by bottom board,and the contributing rate is depended on belly-board and bottom board rigidity. |

| Keywords: | bridge construction load mode trunk pile rigidity crossbeam inner force |
