Temperature Stress Analysis of Gate Piers at Different Pouring Heights
YU Yang
Abstract：Hydraulic gate piers are common large volume concrete structures in hydraulic structures,and their temperature stress control is the core element of preventing and controlling temperature cracks.The variations of temperature stresses under different pouring heights of gate pier structures were analyzed combined with examples,the law of temperature stress variation with pouring height was clarified,and the temperature conduction path and mode of the gate pier were revealed combined with the special dimension structure of the gate pier.The results indicated that for the large volume concrete structures with gate pier types where the length was much greater than the width,the temperature stress increased first and then decreased with time,and the maximum temperature stress increased first and then decreased with the increase of the gate pier height.In the project of this paper,the temperature stress was maximum when the gate pier height was 4 m.
