摘要
结合某高层建筑纠倾迫降工程实例,对侧限桩约束地基变形进行室内模型试验,研究分析基础沉降量随荷载的变化规律,并利用有限元软件ABAQUS对地基应力分布进行分析,结果表明:侧限桩在一定程度上约束地基土体的竖向变形,并将附加应力向深度范围传递。可为纠倾工程提供参考。
Based on rectification and landing of a high rise building,an indoor model test is carried out on the deformation of the foundation with the restriction bylateral restraint pile,the study analyzes the foundation settlement changing with the load,and foundation stress distribution is analyzedby using the finite element software ABAQUS.The results show that the vertical deformation of the foundation is restrained to a certain extent by the lateral restraint pile,and the additional stress is transferred to the depth range,which can provide reference for the rectification engineering.
