| 摘 要： | 软基边坡处理中常采用水泥土搅拌桩复合地基。但受水平推力作用时桩体存在弯折效应且施工时易出现劣质层。本文采用水泥土连拱抗滑墙加固软基边坡，采用数值分析的方法建立三维模型，分析加固前后边坡的水平侧移、沉降、应力、边坡稳定性的变化，并深入的分析了连拱抗滑墙抗滑机理。研究表明连拱抗滑墙加固边坡技术具有性能可靠、施工方便的优势，在软基边坡加固领域具有广阔的应用前景。

| Abstract: | In the soft subsoil of slope,soil cement piles will bear lateral forces from slope sliding potential,which will cause pile crack because of poor tension strength of soil cement.A new structure of cement-soil mixing pile is raised to improve the anti-slide reinforcement of soft ground embankment.The numerical simulation method is employed to ana-lyze the structure by the dimensional models.Referring to the analysis of the results,displacement,settlement,stress, slope stability conditions after reinforcement.The cement-soil arched walls could make well performance and convenient construction.There is a great application prospect in fields of soft ground slope reinforcement. |
