| Abstract:Taking Liudong New District of Liuzhou City as an example, the flood interception ditch and slope retaining project is introduced with analysis of a section of high slope with elevation difference of 25m. Stability evaluation and residual sliding force calculation is conducted for the landslide using the broken line sliding plane transfer coefficient method of limit equilibrium theory. Discussion is made on the design approach for the three layered anchor cable pile sheet retaining wall. The internal force of the anti slide pile body is calculated by both the landslide thrust method and the Coulomb earth pressure method with the structural plan of the pile sheet retaining wall selected through analysis of the internal force of the pile body. The slope protection plan above the retaining wall, the monitoring plan and suggestions during and after high slope construction are introduced. It provides reference for the treatment of high slope landslides in the future. |
