With the continuous development of the transportation system,the construction of high-speed railway projects has been carried out continuously.Among them,the continuous beam project is an important part in the construction of high-speed railway,and the construction quality has been a focus.During construction,cast-in-place cantilever construction is widely used.However,the load capacity and deformation of the box girder are not taken into sufficient consideration,resulting in unsatisfactory pouring effect.Combined with actual cases,this paper expounds the key points of cast-in-place cantilever construction technology of high-speed railway continuous beam project,and proposes measures to improve the load strength of box girder and effectively avoid deformation.The final results demonstrate that the method is scientific and effective,and can ensure that the height difference of the project is within the range of 5.0 mm,which significantly improves the construction quality.
