Problems solved by technology

[0004] However, the long-term deformation monitoring of traditional ultra-long asymmetric long-span continuous bridges uses manual timing monitoring, which is greatly affected by external meteorological conditions, and cannot achieve long-term stable data collection. The accuracy is low, and all are single monitoring and system integration. Low, it is impossible to conduct a comprehensive analysis of multiple deformation indicators directly, and the accuracy is poor

Abstract

The invention discloses a monitoring system for long-term deformation of an ultralong asymmetric long-span continuous bridge. The monitoring system comprises a mobile platform component capable of moving, a host connected with the mobile platform component, and a first sensor arranged on the mobile platform component, wherein the mobile platform component is arranged on a bridge main body; the mobile platform component is used for detecting a target object, determining the orientation of the target object and moving on the basis of the position of the target object; and the first sensor is used for detecting environment temperature and strain of the target object and outputting received temperature and strain signals to the host. The monitoring system has the advantages of good automationdegree and high monitoring accuracy.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, more specifically, the invention relates to a long-term deformation monitoring system and a control method of a super-long asymmetrical long-span continuous bridge. Background technique [0002] Long-span prestressed concrete continuous girder bridge is one of the most commonly used urban bridges. With the continuous improvement of material performance and construction technology, long-connected and long-span continuous bridges have become an important development direction of urban prestressed concrete continuous bridges, and there are many ultra-long-connected and long-span prestressed concrete continuous bridges with a length of several kilometers. Among them, high static indeterminate times, many system conversion times, large cumulative shrinkage and creep, and obvious temperature effects are the remarkable characteristics throughout the life cycle of ultra-long-span ...
