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.
