Paper Title:
Analysis of Stress Measuring and Testing of Continuous Rigid Frame Bridge
  Abstract

According to the structure and construction features of prestressed concrete continuous rigid frame bridge, with reference to the principle of vibrational chord strain gauge to concrete, the vibrational chord strain gauges to concrete are used in the construction control of prestressed concrete continuous rigid frame bridge. This paper introduces the measurement techniques and methods for stress and strain of main girder of the bridge, analyses some infection factors of stress measuring and testing, and presents the error analysis methods of stress measuring and testing and calculation methods of true stress of structure. The techniques and analysis methods prove to be quite effective through the applications and provide background data for constructing safely of prestressed concrete continuous rigid frame bridge.
