| Abstract: | 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... |
