摘　　要：墩身是公路桥梁工程的重要承重构件。墩身混凝土开裂问题较为常见,这一质量问题增大了公路桥梁结构的质量安全风险。随着公路桥梁数量的增多、规模的扩大,对墩身混凝土开裂的防治愈加重要。基于此,论文对公路桥梁墩身混凝土开裂的原因进行了分析,提出了有效的防治对策,对提升墩身结构性能有着指导意义。Pier body is an important load-bearing component in highway bridge engineering, the problem of pier body concrete cracking is more common, it increases the quality and safety risk of highway bridge structures. With the increase in the number and scale of highway and bridge construction, the prevention and treatment of pier concrete cracking has become more important. Based on this, this article analyzes the reasons for the concrete cracking of highway bridge piers and puts forward effective prevention and control measures, which have guiding significance for improving the performance of the pier structure.
