摘要

为研究整体式墩木对船坞底板及基础的影响,对比计算独立式墩木使用时底板及基础的受力情况.从不同厚度的角度分析并优化调整整体式墩木的结构并计算整体式墩木使用时底板及基础的受力情况.分析了是否考虑桩土共同作用对桩基反力结果的影响.研究结果表明:独立式墩木使用时底板及基础受力不满足要求;整体式墩木能够使荷载更均匀,改善底板的受力状况,使底板内力、裂缝满足要求;当考虑桩土共同作用时,桩基反力会减小.当遇到纵向线荷载大于原船坞设计的线荷载工况时,可优先考虑整体式墩木.该结果可为以后类似的工程提供参考.

关键词： 整体式墩木; 独立式墩木; 荷载均匀

Abstract

In order to study the influence of the whole dock block on dock floor and foundation, the force condition of dock floor and foundation is calculated and compared under working conditions of independent block. From different thicknesses, the structure of whole block is analyzed and optimized, and the force condition of dock floor and foundation is calculated under working conditions of the whole block. The influence of pile-soil co-reaction on pile foundation is analyzed. The results show that the force condition of dock floor and foundation cannot meet the requirements when using independent block. The whole block can make the load more uniform, improve the force condition, and make force and cracks meet the requirements. When pile-soil co-reaction is considered, the pile force will be reduced. When the longitudinal line load is greater than that designed for the original dock, priority should be given to the whole block. The results can provide reference for similar projects in the future.

Key words： whole dock block; independent dock block; uniform load
