Abstract
To investigate the differences in displacement stability between sheet pile revetments and driven close-fit sheet pile revetments,and to clarify the applicable scenarios of these two revetment structures under varying earth-retaining heights and soil conditions,the study first compares and analyzes the force mechanisms of driven close-fit sheet piles and sheet piles,highlighting their core differences in load transfer and stress distribution.This paper then systematically introduces the displacement calculation theories for both types of sheet pile revetments,specifying the calculation models and key parameters.Through soil analysis,internal force calculations,and displacement comparisons,combined with internal force analysis diagrams and displacement tables,the study explores the displacement variation patterns of the two structural forms.The findings indicate that under different earth-retaining heights,the displacement differences between driven close-fit sheet piles and sheet piles are significant.Under general soil conditions,when the earth-retaining height is within 2 m,the displacement of sheet piles is 10%-15%greater than that of driven close-fit sheet piles;when the height exceeds 3 m,the displacement of sheet piles is 30%greater than that of driven close-fit sheet piles.These results provide theoretical foundations and engineering references for the structural selection and displacement control design of revetment projects.关键词
