摘要
本研究旨在探讨土钉支护技术在不同摩擦角和坡度条件下对边坡稳定性的加固效果。采用简化毕肖普法,通过数据模拟分析土钉长度与直径比(L/d)对边坡安全系数的影响。研究中设置了土钉直径、长度、间距及边坡角度等多个参数,结合沙质土边坡的特性,模拟了不同条件下的边坡加固情况。结果表明,边坡的安全系数随土钉L/d值的增加而增大,但当L/d超过有效值时,安全系数趋于稳定。有效L/d值在不同坡度条件下有所不同,范围为400~650。本研究为土钉加固边坡的设计提供了参考,优化了土钉支护技术在不同边坡条件下的应用,有助于提高边坡稳定性,减少滑坡风险。
This study aims to explore the reinforcement effect of soil nail support technology on slope stability under different friction angles and slope conditions.Using the simplified Bishop method,the influence of soil nail length to diameter ratio(L/d)on slope safety factor is analyzed through data simulation.The diameter and length of soil nails were set in the study Multiple parameters such as degree,spacing,and slope angle were combined with the characteristics of sandy soil slopes to simulate slope reinforcement under different conditions.The results indicate that the safety factor of the slope increases with the increase of soil nail L/d value,but when L/d exceeds the effective value,the safety factor tends to stabilize.The effective L/d value varies under different slope conditions,ranging from 400 to 650.This study provides a reference for the design of soil nail reinforced slopes,optimizes the application of soil nail support technology under different slope conditions,and helps to improve slope stability and reduce landslide risks.
