| Abstract: | The north approach bridge＇s 40 m cast-in-place box beam is designed to have the minimum radius of 420 metres and the maximum transverse slope of 5% for Liaohe super large bridge which is located mostly on a soft foundation.Based on the site condition,we adopted the fabricated steel pipe pile limited brackets scheme.Practice shows that the scheme has ensured the safety and quality of engineering and shortened the construction period.It may serve as references for similar engineering. |
