摘　　要：为及时掌握某非对称外倾蝴蝶拱桥变形状态,提出利用静力水准仪进行桥梁关键截面变形的自动化监测预警。文章介绍了静力水准仪的测量原理及系统组成,以某非对称外倾蝴蝶拱桥主梁监测系统的设计为例,介绍了主梁变形监测测点布置方案与阈值设置方法,并将控制截面测点数据与人工监测数据进行了对比。结果表明:基于静力水准仪的变形监测系统具有测量精度高、实时性好、受环境影响较小等特点,可以有效用于蝴蝶拱桥主梁变形监测。In order to grasp the deformation state of an asymmetric cambered butterfly arch bridge in time,the automatic monitoring and early warning of key section deformation of the bridge by using static level is proposed.This paper introduces the measurement principle and system composition of the static level.Taking the design of the main beam monitoring system of an asymmetric cambered butterfly arch bridge as an example,this paper introduces the layout scheme of the monitoring points of the main beam deformation and the threshold setting method,and compares the data of the monitoring points of the control section with the manual monitoring data.The results show that the deformation monitoring system based on static level has the characteristics of high measurement accuracy,good realtime performance and less affected by the environment.It can be effectively used for the deformation monitoring of the main beam of butterfly arch bridge.
