| Abstract: | In construction of the 252m no-seam basement head plate, engineers adopted many comprehensive anti-crack technologies such as prestress, post-pouring zone and so forth, studied some aspects of a cohesive prestressed flat plate such as design principles, construction methods, anchor systems and so on, and researched prestressed loss control methods and anti-crack control methods of ultra-long structures. |
