摘要
为了及时发现斜拉桥的过大变形,避免影响桥梁的正常使用,通过采用合理科学的观测方法定期对其进行变形观测,经综合分析,确定及时有效地运营管理措施与维修养护方案,合理地延长斜拉桥的使用年限和确保其使用的安全性。本文结合咸阳市渭河斜拉桥变形观测实例,探讨斜拉桥变形观测中的观测内容、观测的方法、观测数据的处理方法及精度分析等有关技术问题。
In order to discover the large deformations of the cable-stayed bridge in time and ensure normal use of the bridge,it is necessary to carry on distortion observation regularly through rational scientific method.In addition,by synthetic analysis,it is also useful to determine a effective timely operation control measures and maintenance scheme to prolong the service life of the cable-stayed bridge and guarantee its security use.Taking the distortion observation of cable-stayed bridge of Weihe river in Xianyang city for example,this paper discusses the technological issue concerned with distortion observation such as observation content and method,treatment method of observation data and precision analysis etc.
