摘要
运用赤平投影法、极限平衡法及有限元强度系数折减法,分析了云南安楚公路红层顺向切层路堑边坡的稳定性。结果表明,雨季时边坡不稳定,遂采用预应力锚索与节点锚杆框架梁予以加固。边坡防护工程已于2005年完工,至今未出现任何变形迹象,证明其措施安全可靠。
The stability of bedding slope in red beds along Yunan Anning-Chuxiong Highway is analyzed using equatorial projection method,limit equilibrium method and strength reduction finite element method.The result shows that slope is unstable in rainy season,so it shall be reinforced using prestressed anchor cable and jointed anchor frame beam.Slope protection project has been completed in 2005 and no deformation has occurred until now.It is proven the reinforcement measure is safe and reliable.
