红砂岩路堑边坡岩体破碎 ,适宜用锚杆骨架梁护坡 ,本文对采用锚杆骨架梁护坡后的边坡 ,按虚拟重力式挡墙进行稳定性分析 ,然后采用平面有限元分析锚杆受力和边坡受力情况。结果表明 ,边坡的锚杆深度在 5 m左右较为合理 ,锚杆主要起联结破碎岩体和支撑混凝土骨架作用 ,对边坡设计有一定的指导价值。
The rock mass of the red sandstone cutting slope is broken and suitable for slope protection with the anchor skeleton beam. In this paper, the stability of the slope after the slope protection using the anchor skeleton beam is analyzed by virtual gravity retaining wall. Then, Force and slope stress situation. The results show that the depth of the rock bolt is about 5 m, and the anchor mainly plays the role of coupling broken rock mass and supporting concrete skeleton, which has certain guiding value for slope design.
