摘　　要：西成客专阿房宫车站路基桩板结构中采用旋挖钻机在建筑垃圾层中进行桩基成孔,论文以此为基点,介绍了在4~16m厚建筑垃圾层中采用旋挖钻机并使用双护筒配合成孔的灌注桩施工技术的应用,实践证明,效果显著,可为类似不良地质条件下采用旋挖钻机快速施工桩基提供技术参考。The construction of pile-foundation holes in the pile-slab structure of the roadbed of the west-made passenger special station is based on this basis,this paper introduces the application of the construction technology of Cast-in-place pile with rotary drilling rig used in 4 ~16 m thick building waste layer and using double sheath and hole,and the practice proves that the effect is remarkable,which can provide technical reference for using rotary-digging rig to quickly construct pile foundation in similar unfavorable geology condition.
