This paper focus on the feasibility study on combination of seal and extrusion to hole formation and rammed cement soil pile, and its application on wet and sinking loessial area; gave a research method of bounds replacement rate for eliminating the wet or sinking of loessial area; and study on value access method of bearing capacity parameter for technology calculation.

结合了具体工程实践，本课题的主要研究内容：①研究挤密成孔法与夯实水泥土桩组合的可行性，及在湿陷性黄土地基中的应用；②给出使黄土湿陷性消除的界限置换率研究方法；③对采用此工艺计算承载力时参数的取值方法进行研究。

The new ideas from this paper: using mechanics principle study of soil, create a practical test to prove that it could change the physical mechanics character of base soil completely, reducing distortion, improving strength, and eliminating wet or sinking of base soil by seal extrusion during hole formation process at certain replacement rate; it could strengthen the loessial soil base to high bearing capacity to standard value of 300 to 400kPa through seal extrusion to hole formation technology together with rammed cement soil pile. Some value of the parameters adopted by bearing capacity calculation of the composite base of rammed cement soil pile with seal extrusion to hole formation exceeded the criteria of 'Technical Regulation on Building Ground Treatment'.(JGJ79-2002) This technology meet the design requirements and save investment.

本课题的创新点：1 利用土力学原理进行研究及理论推导，并经实践：证明了在置换率为某一定值的情况下，在成孔过程中通过挤密作用可以从根本上改变地基土的物理力学性质，使地基土的变形减小，强度提高，湿陷性消除；2 挤密成孔工艺与夯实水泥土桩的组合，可使低强度的湿陷性黄土地基变成高强度的复合地基，其承载力特征值可达 300~400kPa；3 挤密成孔法夯实水泥土桩复合地基承载力计算所采用的有关参数取值范围超出了《建筑地基处理技术规范》JGJ79-2002 中的有关规定；4 在节省投资的前提下，解决了地基高承载力、低变形及黄土湿陷性问题，达到了设计要求。
