云南220 kV 路德变电站填方高边坡稳定性分析与治理

摘要

By adopting 2-Dimensional limit equilibrium theory-simplified Bishop method,the paper undertakes the stability analysis of 220 kV Lude substation in Yunnan,concludes the safety coefficient of the fill slope is lower,adopts the support measure with reinforced geo-grid and bot-tom rubble stone retaining wall,designs the reasonable drainage measures,and concludes the safety coefficient meets the regulation’s demands after the stability analysis of support.%通过二维极限平衡理论———简化Bishop法，对云南220 kV路德变电站进行稳定性分析，得到填方边坡安全系数偏低，采用加筋土格栅与底部毛石挡墙相结合的支护措施，并设计了合理的排水措施，支护后边坡稳定性分析得到安全系数满足规范要求。
