大跨径混凝土箱梁桥腹板受力研究

The web plate stress research on long-span concrete box-girder bridge

从理论上探讨了腹板主拉应力的理论计算公式,并以具体的工程实例对箱梁腹板主拉应力值进行了理论计算和分析,研究了该桥在各工况下的应力变化规律,得出了有用的结论,其结果为桥梁的施工控制提供了可靠的数据,确保了施工质量。

This paper has discussed the main tension theoretical calculation formula of the web plate theoretically, and has carried on the theo- retical calculation and the analysis by the concrete project example to the web plate main tension value of the box-girder. Has studied this bridge＇s stress variation rule under various changes of condition, and has drawn the useful conclusion. The results for the bridge construction control provides a reliable data, and guaranteed the construction quality.
