重力式码头加固升级增设卸荷平台改造与应用

Transformation and application of modifying gravity wharf by adding unloading platform

针对升级改造中使用荷载增加较大的重力式码头结构稳定性、承载力不能满足规范要求的情况,提出码头墙后增设桩基及简支板平台、形成卸荷平台减少土压力的方案,计算分析表明,卸荷平台对提高结构稳定性、承载力和减少地基应力有显著作用。探讨其优缺点和适应性。

For the case that the gravity wharf has large load increasing after the upgrading and rebuilding, the structure stability and the bearing capacity can t meet the specification requirements. The method of adding e stability and bearing capacity of the structure and reducing the foundation stress. The advantages and disadvantages and adaptability of this structure are studied after.
