摘要
陕北某电厂人工高边坡岩土组合复杂,存在黄土、粉土、中细砂及砂岩、泥岩,岩体抗风化能力差,且坡体中部有断层通过.人工开挖后边坡坡顶、坡面发生明显变形破坏,并有进一步发展的趋势.通过对边坡的变形破坏模式分析,提出了以锚杆框架格构、锚筋桩框架格构为主,并采取不同坡比分级放坡的边坡治理方案.三维模拟结果和施工完成后位移监测资料显示,该边坡处理方案符合边坡工程地质条件,能恰到好处地平衡边坡开挖后的应力应变的改变,工程措施达到了安全、经济的目标.
For a cutting high slope in North Shaanxi,the soil and rock of the slope is composed of loess,silt,fine sand,medium sand,mudstone and sandstone,which are of weak anti-weathering ability.And there is a fault passing through the slope.Obvious distortion and failure occured at the top and surface of the slope after excavation.The distortion and failure still have a developing trend.Based on the failure mode analysis,teatment measures combining the lattice frame anchor structure and lattice frame steel piles wi...
