| Abstract: | Principle and method of vertical and stress control were put forward.Construction control of certain large span prestressed concrete continuous rigid frame bridge was taken for example,Dr.Bridge,a bridge structural analysis program used for construction and design,was applied to build computation model and calculate behavior of structure.Parameter identification of error analysis was based on the least square method;method of state forecasting was used to control elevation and stress.After closure of bridge... |
