黄土地区高陡斜坡溜坍下滑治理研究

Research on Treatment of High and Steep Slope Collapse and Sliding in Loess Areas

根据黄土高陡斜坡溜坍下滑的现状、特点、地质情况等,应用预应力锚索锚固桩预加固坡脚,通过检算各级边坡的最不利圆弧滑动面,设置锚索格梁、十字形锚杆格梁加固防护各级边坡,可有效治理高陡斜坡的溜坍下滑。研究阐明本项目的边坡设计参数、设计检算与工程设置情况,为类似工程设计提供参考。

In view of the current situation, characteristics and geological conditions of high and steep slope sliding in loess areas, prestressed anchor pile is applied to pre-reinforce the toe of slope. Based on the calculation of the most unfavorable circular slipping surface of slopes at all levels, anchor cable lattice beam and cross type bolt lattice beam are set up to effectively reinforce and protect the slopes. This paper studies and defines slope design parameters, design verification and engineering configuration and provides references for the engineering deign of similar projects.
