摘要
将板拉桥拉板离散为格栅结构，在此基础上探讨板拉桥拉板形成后斜拉索索力的计算方法．通过对两种理想情况：考虑粘结且斜拉索与普通钢筋混凝土板变形协调及不考虑粘结且不计斜拉索与孔道摩擦的分析计算。
This paper probes into an approximate calculation method for the cables' forces of board stayed bridges through the discrete topology of grid structure after the boards are formed.It concludes that the cable forces may be obtained approximately from the average values of two ideal cases,considering cohesion and deformation compatibility between cables and concrete board and not considering cohesion and rubbing between cables and concrete board.
