摘要
Abstract
With the w ide application of concrete in engineering, the crack problem has received more attention. Cracks are usually caused by construction or other ext ernal factors, w hich not only affect the aesthet ics of structure, but also affect the structure function because cracks can decrease t he permeability and then induce leaking. In this paper, the spillway concrete lining of Shuan-gquan Reservoir in Anyang County was used as a case study. The finite element model was developed using ANSYS to analyze the varia-tion rules of temperature and stress fields under different working conditions, and to investigate the causes of cracks in the concrete lin-ing and initial position of cracks. The measures for temperature and stress control of concrete w ere proposed.关键词
