摘　　要：常规挡土墙一般采用开挖至基础底面后从下往上施工,挡土墙需满足滑动稳定性、倾覆稳定性、地基承载力及墙身材料强度等要求。对高陡边坡来说,还应注意施工时墙背土体稳定确保施工安全;常规挡土墙在高陡边坡的应用难度增大。近些年,山坡地错台建筑越来越多,不仅要求挡土墙具挡土功能,还要求挡土墙顶面能承受较大竖向荷载(如满载消防车载要求),能有效控制水平位移,且具有一定的抗震能力。本文针对常规挡土墙在高陡边坡中应用的难度,探索锚杆式挡土墙和墙背填土注浆加固处理相结合的改进型锚杆扶壁挡土墙的应用可行性和支挡效果,为挡土墙应用于高陡边坡支挡积累经验。Conventional retaining wall generally use the excavation to the bottom surface of the base from bottom to top after construction, retaining wall must satisfy the sliding stability, overturning stability, bearing capacity of ground and wall body material strength requirements. The High and steep slope, but also should pay attention to during the construction of the wall back soil stability to ensure construction safety, conventional retaining wall in high and steep slope increased the difficulty of application. In recent years, the wrong station buildings are more and more, not only requires the retaining wall with retaining function, but also for retaining wall top surface can withstand a larger vertical loads (such as full of fire vehicle requirements), can effectively control the horizontal displacement, and has better seismic capacity. In this paper the conventional retaining wall in high steep slope in the application of the difficulty, exploring the anchor retaining wall and the wall backfill grouting reinforcement in the combination of improved type anchor buttress retaining wall applied feasibility and supporting effect, for retaining wall applied in high and steep slope supporting experience.
