摘要
本文应用三弯矩方程和力的叠加原理,研究公路工程中等截面连续梁桥在汽车荷载、人群、恒载作用下的受力计算问题,并推导出支点截面最大负弯矩和跨中截面最大正弯矩的计算公式,最后通过实例说明公式的应用。
In this paper,internal force for dead and live load of highway continous bridge with constant cross section is been studied,using thrice-moment equation method and principle of superposition. And formulue of maximunl negatiue moment at the sapports and postiuc moment at the every midspans is being deduced. At last,some examples are being gived.
