重力式码头加固升级增设卸荷平台改造与应用

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。

Transformation and application of modifying gravity wharf by adding unloading platform

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 pile foundation and simply supported slab platform to form the unloading platform is proposed,which can reduce the earth pressure.The calculation result shows that the unloading platform has significant effect on improving the stability and bearing capacity of the structure and reducing the foundation stress.The advantages and disadvantages and adaptability of this structure are studied after.
