  12. The paper draws some valuable conclusions : the limited bearing capacity of manual excavation filling pile is much higher than the limited bearing capacity of machine drilled filling pile ; through grouting injection around the pile shaft, the pile bearing capacity can be effectively improved ; proportion of resistance force around the pile side in total load is much larger than that of pressure on the pile tip, and the intensity of resistance force around the pile side is 30 - 50kpa on average
