Furthermore,the assembly location,welding,arching,unloading and deflection observation are introduced during construction.

Based on the project of plate-loading test program for the suspension bridge of Runyang Bridge,the article studied on the method of the deflection deformation survey for a large-sized bridge with total station instrument.

Method of laser & imaging deflection measurement;

Study on stability of laser & imaging deflection measurement system;

This paper introduces a monitoring system based on deflection measurement of the bridge.

Interpolation analysis on the deflection measurement data of arch bridge

New development of slab deflection measurement for high Concrete Faced Rockfill Dam(CFRD) is introduced.

The basic principle of the sensor is introduced,the composition of connected pipe opto-electronic deflection measurement system is discussed,and it is practically applied in the deflection monitoring of Dafoshi Yangtze River Bridge.

Application of connected pipe optoelectronic liquid level sensor in bridge deflection monitoring;

Based on the deflection monitoring project in Yangtze River bridge,this paper describes the method of deflection deformation monitoring,the arrangement of measuring points,the monitoring accuracy,and the data processing for long span pre-stressed concrete continuous box beams.

According to the characteristic and demand of the bridge vibration measurement, the linear CCD detect technology is chosen t to realize the non-contact and mobile automatic measurement.
