Analysis of the Interaction Effect of Different Pile-anchor Combination Structures in a Deep Foundation Pit
Taking the deep foundation pit of a super high-rise building in Yichang as an example,by es-tablishing a three-dimensional finite element model,the internal force of the support structure and the de-formation evolution law of the foundation pit under different support combinations are studied in this pa-per.Combined with the deformation monitoring data of different stages of foundation pit excavation,a multi-dimensional space model verification method based on the displacement of support piles and the in-ternal force of anchors in typical parts is proposed.The law of change of internal force of different support combinations and the interaction of support combination structures in the process of deep foundation pit excavation are further revealed according to the calculation results.The research results can provide a ba-sis for the selection of combined support design schemes for deep foundation pits,which is of great engi-neering significance for the development of deep foundation pit deformation control technology.
