Low precision in closure and in appropriate track configuration of built bridges is a general problem in the construction of cantilever-concreting railway bridges.

The hanging basket is one of the major ways in cantilever construction,and its design is closely related to the quality of the whole bridge construction.

Internal force control methods for cantilever constructiong PC level curved girder bridge are studied.

Shagang Bridge on Chang-Wan Highway is 486m high, 12 5m wide, with main span made of 75m+75m cantilevered concreting box girder.

Combining with construction practice, six technical key problems in the con-struction of cantilevered concrete pouring of continuous beam are discussed, including large a-mount concrete pouring in one time,de formation control for large span continuous beam,preven-tion concrete from crack and structural system transform etc.

In order to solve the problem about setting 0# block bracket for cantilever perfusion beam with single pile and column pier, the stress system that setting double-cantilevers beam on embedded brackets can be adopted.
