Spatial Deformation Calculation and Parameter Analysis of Pile–Anchor Retaining Structure

Scholars often consider the deformation of a foundation pit retaining structure as significant indicator its stability. However, current theoretical prediction formula for with pile–anchorretaining is not yet perfect. This study utilizes simplified spatial model and principle minimum potential energy to derive structure’s deformation. Afterwards, numerical simulation developed based on actual engineering practices. On-site monitoring data compared results calculation formulas models validate their applicability. The research findings reveal minimal discrepancies between results, outcomes, on-site data, indicating high level accuracy. Those three follow consistent rules. horizontal curve crown beam exhibits ‘V’-shaped distribution, distance from point centerline decreases, increases. pile displays pile’s increases decreases. indicate that increasing size material strength waist has only limited effect controlling by pile, can be significantly reduced.
