摘　　要：双预应力混凝土结构又称为拉-压双作用预应力混凝土结构,是由预拉应力和预压应力混凝土结构组合而成的一种新型结构。由于工作性能上的优越性,目前越来越多应用于实际工程中。相对于普通预应力混凝土梁,双预应力混凝土梁的施工过程比较复杂,一些施工工艺尚在研究改进中。通过后压法双预应力混凝土试验梁的制作过程,对其施工工艺及注意事项进行研究。Bi-prestressed concrete is also called tension and compression double-acting concrete,tension area of which could be made to bear pre-compressive stress and compression area could be made to bear initial tensile stress. More and more bi-prestressed concrete is applied in practical engineering for its advantage. Compared with the prestressed one,the construction process of bi-prestressed concrete is complex. In this paper,construction technology of post-compressive bi-prestressed concrete is analyzed through the making process.
