Take the structure of area A of the rail bearing layer of the high-speed rail station building of Xiong'an New Area high-speed rail station as the engineering background,it studies the change law of temperature and strain of the structure during the construction process.The construction monitoring of the strain and temperature changes of the steel concrete beams in key positions of the structure during the construction process is carried out by means of vibrating string strain gages.The purpose of monitoring,the instruments and equipment used and the monitoring scheme were introduced;The strain and temperature data obtained by monitoring were collated and studied,revealing the variation law during construction,and concluding that the strain and temperature of concrete in the hydration reaction were positively correlated.
