摘　　要：为合理开挖川西混合土路堑高边坡,文中以平台宽度、坡比和坡高3个几何参数作为影响因素,开展不同坡型组合的多级高边坡稳定性研究。研究结果表明,平台宽度、坡比和坡高对边坡稳定性安全系数影响显著,且稳定性安全系数与平台宽度呈线性正相关关系,与坡比和坡高呈负相关关系。研究结果对类似地区多级边坡设计具有一定的参考价值。To reasonably excavate high slopes of mixed soil roadbeds in western Sichuan,this study investigates the stability of multi-level high slopes by considering three geometric parameters:platform width,slope ratio,and slope height.The results indicate that platform width,slope ratio,and slope height significantly impact the safety factor of slope stability.Specifically,the safety factor is positively linearly correlated with platform width,while it is negatively correlated with slope ratio and slope height.These findings provide valuable guidance for the design of multi-level slopes in similar regions.

关 键 词：多级边坡 边坡稳定性 平台宽度 坡比 坡高
