Abstract:
With the w ide application o f concrete in eng ineering , the cr ack pro blem has received mo re attention. Cr acks are usually caused by constr uctio n o r o ther ext ernal factor s, w hich no t o nly affect the aesthet ics of str uctur e, but also affect the str uctur e function because cracks can decrease t he permeability and then induce leaking . In this paper , the spillway concrete lining of Shuan2 gquan Reservoir in Anyang County was used as a case study. The finite element model was developed using ANSYS to analyze the varia2 tion rules of temperature and stress fields under different wo rking conditions, and to investigate the causes of cracks in the concrete lin2 ing and initial position of cracks. The measur es fo r temperature and stress contro l of concrete w ere pr oposed.
