云南220kV路德变电站填方高边坡稳定性分析与治理

The stability analysis and control of 220 k V substation fill high slope in Yunnan Lude

通过二维极限平衡理论——简化Bishop法,对云南220 k V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。

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.
