内河船闸引航道靠船墩结构设计探讨

Discussions on Structural Design of Berthing Pier for Inland Navigation Lock Approach Channel

靠船墩的结构选型和受力计算,是内河船闸引航道靠船墩设计中的重点。本文结合工程实例,采用M法分别计算了采用刚性结构、柔性结构和上刚下柔性结构设计的四种型式靠船墩结构的内力及位移情况,计算结果与方案比选表明钢管桩基础砼承台结构靠船墩作为内河引航道靠船墩结构设计,既经济又实用。

The structural type selection and force calculation of ship pier are the key points of the design of ship lock pier for inland navigation lock approach channel. Combining with the engineering examples, M method is used to ealculatehe internal forces and displacements of four types of ship supported pier structures in this paper. The four structural types are the rigid structure,the flexible structure and the upper rigid lower flexible structure. The comparison of the calculation results and the schemes shows that the structure of concrete pier cap of steel pipe pile foundation is economical and practical in inland waterway ship pier structural design.
