市政道路桥梁设计问题与施工中裂缝成因分析

Analysis on the Design Problems of Municipal Roads and Bridges and the Causes of Cracks in Construction

针对市政道路桥梁工程中存在的荷载设计不合理、材料选择不合理、地基不稳等问题进行讨论,并对施工中不同类型的裂缝进行了成因分析。结合某市政道路桥梁工程实际进行分析,结果表明,经过排水以及荷载设置,并添加了泄水管后的桥梁,稳定性得到了有效提升。

The problems of unreasonable load design,material selection and foundation instability in municipal road and bridge engineering are discussed,and the causes of different types of cracks in construction are analyzed.An example of a municipal road and bridge project is analyzed,and the results show that the stability of the bridge has been effectively improved after drainage,load setting,and the addition of drainagepipes.
