Beschreibung
Zusammenfassung:	The invention discloses an extra-large area concrete construction method, which comprises: computing a temperature stress by a finite-element analysis process; arranging stress bars according to the result of the computation of the temperature stress and design requirements; and tensioning the stress bars. By arranging the prestress bars and generating the prepressing stress in reinforced concrete, air shrinkage generated in the hardening of concrete and tensile stress generated in hydration heat contraction are counteracted basically, so the cracking of concrete are relieved and prevented.
