桩筏基础优化设计研究概述

桩筏基础在各种基础形式中整体性能较好,具有很大的刚度,其在提高竖向承载能力和调整不均匀沉降方面的作用十分显著,因此在高层建筑地基基础选型中被大量选用。由于上部结构形式和地基条件的差异性,目前国内外对桩筏基础的受力及沉降分析仍未形成系统统一的结论,对其优化方式也有不同的见解和结论。文章对目前桩筏基础整体的优化设计研究进行一系列总结,希望对后续的研究有一定的参考意义。

Summary of the study about the optimization design of the piled raft foundation

Among various forms of the foundation,the piled raft foundation has good overall performance and great rigidity.It is very significant in the vertical bearing capacity and adjusting the uneven settlement,therefore it is largely chosen to be the foundation of high-rise building.Because of the difference of the upper structure and the ground condition,the analysis of the piled raft foundation’s stress and settlement have not yet been formed to a system of unified conclusion,and the optimal way also has different opinions and conclusions.In this paper,a series of summary of the study about the overall optimization design of the piled raft foundation are made,hoping to have certain reference function to the further study.
