摘要
通过土样的室内回弹再压缩试验和有限元建模分析,对基底以下各土层的固结—开挖卸荷—再加荷变形规律进行研究。对已有的研究成果进行验证。同时通过Midas GTS NX建立基底地层模型,通过加荷—卸荷—再加荷的荷载施加过程,进行有限元分析,分别得到加桩基和未加桩基工况下的沉降值,为今后类似的工程提供借鉴。
Based on rebound recompression test of different soils,the deformation characteristics of soil samples under unloading were studied.The existing research results were verified.Meanwhile,build layer models by using finite element analysis software Midas GTS NX,after the process of loading-unloading-reloading,the settlement values under different working conditions were obtained.The results may provide useful reference for similar projects.
