摘　　要：针对桥墩微小变形难以发现,易造成较大危害的问题,论文以四川东部的一座预应力混凝土桥为例,分析其工程现状及监测方案优缺点,通过控制网点部署的方式对桥墩变形监测进行监测。监测结果表明,大桥的平面基准网络稳定,符合正常运用标准。所有记录的位移值均在结构设计允许的安全边界之内,没有检测到任何不寻常的突变现象。To solve the problem of small deformation ofbridge piers that is difficult to detect and can cause significant harm,this paper takes a prestressed concrete bridge in eastern Sichuan as an example,analyzes the engineering status and monitoring scheme advantages and disadvantages.By controlling the deployment of network points,the deformation monitoring of bridge piers is monitored.The monitoring results indicate that the plane reference network of the bridge is stable and meets the normal operating standards.All recorded displacement values are within the safe boundaries allowed by the structural design,and no unusual sudden changes were detected.
