摘　　要：针对边坡饱和软土的特殊工程地质条件,对旋喷桩加固处理边坡软土地基进行探讨。进行了水泥土配方和室内外水泥土立方体强度试验分析,并结合原位试验探讨了旋喷桩、复合地基承载力和沉降的分析计算方法。旋喷桩桩端嵌入稳定层并在可能滑动面区域采用复喷,可有效地提高复合地基抗剪强度和边坡稳定性,同时可提高复合地基承载力,减少复合地基沉降。According to the special geological condition, soft soil slope treatment using jet grouting pile was studied. Cement soil ration and cubic compressive strength of cement soil were analized both in laboratory and site. Combined with the site test, the method of determing bearing lapacity and settlement of the composite foundation with jet grouting pile were also discussed. The study showed that the pile end embedding into stable soil layer and double jetting in the potential sliding region could effectively improve the shearing strength and the slope stability, increase the bearing capability and decrease the settlement of the composite foundation.
