摘要
针对云南某高速公路在建桥梁大悬臂预应力混凝土盖梁开裂情况,从施工支架和设计方面进行了分析,并采用有限元软件进行了模拟计算,分析了病害产生的原因,所得结论和建议可供同类结构设计和施工参考。
Based on the transverse crack analysis of a long cantilever prestressed concrete bent cap in a highway bridge under construction in Yunnan,this paper analyzed the bent cap bracket and design,carried out the simulation calculation using the finite element software,and analyzed the reason of the transverse crack.The conclusions and suggestions could be used as reference for the bridge design and construction in similar projects.
