摘要
在箱梁空间分析的基础上,找到了通过调整σx、σy,可以对主拉应力进行控制调整,从而达到控制裂缝的目的。并以此作为依据,结合具体工程,对混凝土箱梁桥腹板裂缝进行进一步的探讨,对今后的混凝土箱梁桥的设计具有一定的参考作用。
Based on spatial analysis of box girder,main tensile stress is controlled and adjusted through adjusting σx、σy to control crack.Based on this and combined with practical engineering,web crack of concrete box girder bridge is discussed,providing references for future design of concrete box girder bridge.
