摘要
本文适用于单塔、双塔及多塔斜拉桥主梁的内力分析，其结构可以对称或非对称，作用于主梁上的荷载可以是均布恒荷载、集中恒荷载或活荷载，局部均布恒荷载或活荷载，主梁视为具有混合支座（刚性支座和弹性支座）的连续梁，是超静定结构，用力法建立变形相容方程式便可得到解答。
This paper presents the result for analysis of internal force of main girder of stayed -cable bridge with the type of single tower,double towers and multi-towers,the structure can be symmetric or unsymmetric,and the load on the main girder can be even-distributing constant load, concentrated constant load or changing load, partly evendistributing constant load or changing load. The main girder can be considered as the continuous girder with combined support (rigid support and elastic support),it is a hyperstatic structure,and the result of internal force analysis can be gained by using the stress analysis method to set up deformation correlation formula.
