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.

The continuous beam cantilever grouting construction of Lushui doublet super large bridge over Zhe-Gan line

The article makes detailed presentation of construction methods and techniques used in the cantilever concreting of the main Yinhe Bridge with form-traveler.

Control technique for construction of pre-stressed-concrete cantilever casting bridge;

Youdungang Bridge is a continuous box girder bridge with the main span of 80 m in Qingpu Area,Shanghai,which has adopted cantilever casting.

At present,cast-in-place cantilever method is mainly used to construct the long span pre-stressed concrete continuous rigid-frame bridges.

The simulated pressure test of the hanging basket of main equipment of cast-in-place cantilever method was carried out,every forcing data of main beam construction were pointed out so as to guarantee the construction quality of bridge main beam.

In the recent years,the cast-in-place cantilever method for the construction of the prestressed concrete continuous bridge has been rapidly developed in our country,which put forward very high requirements for many aspects of the design and construction.
