| 摘 要： | 本文建立了受渗流作用的温度场数学模型。通过有限元计算,分析了渗流场对瞬态温度场的影响,结果表明渗流使得拱坝拱端区域温度降低,从而使拱坝温度荷载减小。拱坝设计规范没有考虑渗流对拱端这样特殊部位的影响,温度荷载计算偏于安全。

| Abstract: | A mathematic model that was about temperature field with influence of seepage field was created in this paper. Through finite-element analysis, the result demonstrated that seepage made temperature of arch dam abutment decreased, which induced temperature load reduced. Arch dam design criterion did not take privileged sites into account, like arch dam abutment, calculation of temperature load leaned to conservatism. |
