摘　　要：本文在工程实例基础上,分析了预应力曲梁的受力变形特点和施工特点,探讨了其设计、计算和施工方法.着重推导和建议了预应力损失计算公式.最后给出了工程实例.On the base of a project, both the behaviors of stress and deformation and the properties of construction of the prestressed spatial girder were analyzed. Moreover, the method of design, calculation and construction were discussed. The formula for the estimation prestress loss were derived and advised. Finally, an actual example was analyzed.
