摘　　要：结合一典型模型的理论推导和对深圳市宝安体育场的有限元分析,研究了施工环境温度对车幅式张拉结构成型后索力的影响。为了防止索力偏离设计值过大,从理论上提出了3种消除温度影响的措施,并通过宝安体育场的算例进行了校核。Theoretical derivation for a typical structural model and finite element analysis of Bao＇an stadium in Shenzhen were carried out in order to investigate temperature effects on cable force.Obvious deviation of cable force from its design value was not expected,so three measures for correcting deviation of cable force were proposed for Bao＇an Stadium,and it will remove the temperature effects mentioned above.These measures were proved to be effective in Bao＇an Stadium.
