| Abstract: | This paper illustrates height control in pre-stressed concrete continuous beam bridge construction and its importance,establishes computing model of cantilever deflection by finite element method considering the creep of concrete,and draw a conclusion that the computing result is rather identical with that of field measurement,which to offer a reference for the control of bridge height. |
