摘　　要：为分析水利工程中U型槽式挡土墙的优势和特点,进一步探究内撑梁对挡墙结构内力及变形的调节作用,综合比较了常见型式挡土墙的主要优点和不足,初步分析了U型槽式挡土墙设计要点,并以安徽省淮河流域南润段蓄洪区润左保庄圩上的尤东新站排涝出口挡土墙工程为实例,通过对比多组不同高度、跨度的U型槽挡墙结构内力和变形,重点探讨了内撑梁对挡土墙结构内力分布和变形调节的影响规律。结果表明:U型槽式挡土墙在结构安全、施工便利、工程造价等方面优势明显,能很好地应用于水利工程中;内撑梁对U型槽式挡土墙结构的最大弯矩、剪力及变形都具有显著调节作用,能够大幅度提高结构安全稳定性。To analyze the advantages and characteristics of U-type groove retaining walls in hydraulic engineering,and further explore the role of internal support beams in adjusting the internal forces and deformations of the wall structure,this study comprehensively compared the main advantages and shortcomings of commonly used types of retaining walls.The key design points of U-type groove retaining walls were preliminarily analyzed.Using the example of the Youdong Xinzhan drainage outlet retaining wall project on the Runzuo Baozhuang weir in the Nanrun section of the Huaihe river floodplain in Anhui Province,the study compared multiple sets of U-type groove retaining walls with different heights and spans.The focus was on exploring the impact of internal support beams on the distribution of internal forces and deformation adjustments in the retaining wall structure.The results showed that U-type groove retaining walls had significant advantages in terms of structural safety,construction convenience,and project cost,making them highly suitable for application in hydraulic engineering.The internal support beam had a significant adjusting effect on the maximum bending moment,shear force,and deformation of the U-type groove retaining walls structure,greatly enhancing the structural safety and stability.
