Case Study for the Influence of Uplift Pile Arrangement Type on the Internal Forces of the Foundation
-
摘要: 针对有抗浮需求的某工程,在确定抗拔桩根数后,借鉴工程常用布桩方法,分别对集中布桩、均匀布桩和板中布桩三种布桩型式进行研究。用岩土工程有限元数值软件MIDAS/GTS[1]对三种布桩型式进行分析,并改变水位高度,将不同布桩型式在不同水位下底板和地基梁弯矩值进行比较,得出底板及地基梁弯矩值在低水位工况下集中布桩最小、在高水位工况下板中布桩最小的结论。Abstract: In order to ensure the safety and normal use of buildings,the uplift pile should be used when the underground water level is high.By using MIDAS/GTS to calculate the foundation slab and beam bending moment of three normal uplift pilearrangement type in actual projects at different underground water level,the best type for certain working condition could be found.
