摘　　要：根据淋溪河拱坝地形、地质以及气候资料,结合拱坝规范利用有限元计算了拱坝稳定温度场。依据经验初步拟定了3组封拱温度方案,通过对坝体应力分析计算,最终确定出对坝体应力最有利的封拱温度,可为后续设计和施工提供理论和技术支持。According to relevant data on terrain, geology and climate of Linxihe Arch Dam, the joint closure temperature of Dam is calculated by FEM. Based on past research experiences, 3 groups of initial joint closure temperature are selected. Through dam structural analysis, the most favorable joint closure temperature is confirmed which can provide theoretical and technical support to future design and construction.
