摘　　要：文中结合具体工程实例,介绍了素砼沉管灌注桩(CFG桩)结合碎石桩形成组合桩型复合地基加固软土地基的处理方法,通过对组合桩型复合地基的施工及静载荷试验,验证了承载力计算方法的可行性。也表明采用此方案加固淤泥质、泥炭质土地基是因地制宜,技术可行,较为经济的地基处理方案。Combined with a concrete project example,this paper introduces the treatment method of combining CFG pile with crushed stone pile to form composite pile type composite foundation to strengthen soft soil foundation,and verifies the feasibility of the calculation method of bearing capacity through the construction and static load test of composite pile type composite foundation.It also shows that this method is suitable to local conditions,technically feasible and relatively economical for foundation treatment.
