| Abstract: | Combining with engineering cases, the reasons caused cracks on over-long concrete structure are analyzed and the construction scheme is proposed. The paper presents the key methods and guidelines of unbonded prestressed concrete construction for the elimination of cracks in the seamless construction. In which the treatment of prestressed late poured band is introduced emphatically. Engineering practice confirmed that this technique is worth to be extensively spread. |
