| Abstract: | The main bridge of an expressway spanning Beijing-Shanghai Railway is a 2×68 m pre-stressed concrete T-shaped rigid-frame bridge by the double-roadway synchronous rotation construction.This kind of bridge is the small influence of scheme on the security of railway operation.The rotation weight is 13 500 t.The article introduces the design characteristics of the main structure and the rotation system of wide-roadway T-shaped rigid-frame bridge by the rotation construction and its structural analysis gist. |
