Abstract
To reveal the mechanical mechanism and parameter optimization rules of the levee reinforcement system with dou-ble-row concrete piles,a pile-soil interaction model was constructed based on finite element numerical simulation technology,and the influence laws of pile length,pile diameter,and soil parameters on levee stability were systematically analyzed.The re-sults showed that the double-row piles form a three-dimensional collaborative loading system through the pile top connecting beam,and their horizontal displacement decayed exponentially along the depth.The pile length and pile diameters had a syner-gistic strengthening effect on the safety factor,and an increase of 0.2 m in the pile diameters was equivalent to an increase of about 2°in the internal friction angle of the soil,revealing the quantitative substitution relationship between soil parameters and pile geometry parameters.The research results provide a parameters optimization basis based on risk control for the design of levee reinforcement,and verify the engineering applicability of the double-row pile system in enhancing flood resistance through stress redistribution and collaborative deformation.关键词
