钢混复合桩吊运工艺分析

钢混复合桩结合了混凝土管桩造价低和钢管桩抗弯性能好的优点,在满足工程质量要求的前提下又达到了降低成本的目的。对钢混复合桩6点吊的设计计算方法进行推导并结合现场试验进行验证,在此基础上探讨了吊桩参数的敏感性,同时依托工程试验分析了钢混复合桩4点吊与6点吊之间的异同,为钢混复合桩的吊运工艺提供参考。

Lifting technology for steel concrete composite pile

The steel concrete composite pile combines the low cost of concrete pipe pile and good flexibility of steel pipe pile,and achieves the purpose of reducing the cost under the premise of meeting the project quality requirement.The design method of lifting steel concrete composite pile with six lift points is derived and compared with field test,based on which,the parameter sensitivity of lifting pile is discussed.Meanwhile,this paper analyzes the similarities and differences between six and four lift points based on field test.The study may serve as reference for the lifting technology of the steel concrete composite pile.
