| Abstract: | Based on the monitoring of construction process of the extra long continuous beam bridge of prestressed concrete,the deflection changes of the continuous beam during construction and stress distribution are studied.According to the construction technology mainly with proper consideration to temperature load, a new closing up criterion is put forward.This new criterion makes the structure in the optimum construction stress state and operation state. |
