摘要
结合某铁路钢管混凝土拱桥的设计与施工过程,分析了施工中拱脚混凝土开裂的原因,并采用有限元分析方法,探讨了结构的受力特征,提出了拱脚破裂事故的处理方案,确保了拱桥运营的安全性。
By combining with the design and construction process of some railway steeltube concrete arch, the paper analyzes the reasons for the cracks on the foot in the construction, using the finite element analysis method, explores the stressed features of the structure, and points out the treatment scheme for the cracks, so as to ensure the safety of the arch bridge operation.
