摘要
辽河特大桥北引桥40 m跨现浇箱梁设计平曲线最小半径为420 m,最大横坡为5%,基础多处于滩涂、水塘等软基地带。根据现场实际情况,选用装配式钢管桩少支架方案。实践表明:该方案保证了安全、质量,节约了工期,应用成功,值得同类工程施工参考。
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.
