摘　　要：西安市某工程根据场地上硬下软的情况,通过比较,选择采用半挤土CFG桩(螺杆桩)进行处理。螺杆桩的钻具输出扭矩大,钻头高强耐磨,成孔场地清土量少,无泥浆污染,施工简单,质量易控且造价低廉,施工实践证明该方法处理效果良好。Considering the hard top and soft bottom of construction stratum of a project in Xi＇an, partial soil squeeze CFG pile（screw pile） is adopted to treat the stratum. Screw pile drill has many advantages, such as large torque output, wearable drill bit, small soil residue after drilling, free of mud pollution, easy construction, manageable quality and low cost. It is proved that this method could realize excellent treatment effect.
