高层建筑桩筏基础中褥垫层厚度的讨论

Analysis on Thickness of Thick in Interaction Between Pile and Soil in Tall Building

用国际通用岩土计算软件FLAC对高层建筑基础的褥垫层厚度进行计算分析,考虑到技术上可靠、经济上合理,褥垫层厚度取10～30cm为宜。在设计桩时,土承担荷载的作用不可忽视。针对工程地质条件,随着荷载的增加,桩的分担荷载基本稳定在70%,这对工程设计有着很大的参考价值。

Thinking about the credibility of technology and the rationality of economy,the thickness from 10cm to 30cm of soil is suitable through the analysis with international civil calculating software FLAC.Because the effect of soil in the load is very important,the function of soil can not be ignored in the designing of pile.According to this geologic condition,the participation load is about 70% with the accretion of all load.It has the important consult value to the engineering design.
