摘要
采用光弹性冻结应力法对网状系杆拱连续梁桥进行了不同工况下的应力分析，给出了边界应力分布和主应力迹线，为优化工程设计提供了参考依据．
By using three dimentional photoelastic frozen stress method, the stresses in a bridge of continuous beam type and with net structured tie rod archs are analyzed. Different working conditions for the bridge are considered. The results are helpful for optimizing the engineering design.
