摘　　要：指出压桩挤土问题虽然有较多的理论成果,但这些理论研究成果与工程应用要求尚有较大差距,通过综合分析压桩挤土问题的机理,探讨了桩孔扩张的空间轴对称和平面应变问题,从而从基本规律或机理上促进桩土作用相关问题的理论和应用难题的研究。It pointed out that pile processing and soil compacting problems had many theoretical results, but these theoretical results had large gap with engineering application requirements. Through comprehensive analyzing pile processing and soil compacting mechanism, the spatial axisymmetric and plane strain problems of pile pore expansion were discussed, therefore improved the theoretical and applied difficult of pile and soil effect problems from basic law and mechanism.
