ANALYSIS ON SOIL DISPLACEMENT CAUSED BY SOIL COMPACTION EFFECT OF THE PRESTRESSED CONCRETE PIPE PILE

Prestressed pile with a pile of quality assurance and inspection easy,on-site construction is convenient and low cost characteristics,in the coastal areas are widely used in soft soil. Prestressed pile belongs to soil compaction piles,pile driving resulting soil compaction effect,if not handled properly the measures will cause the surrounding environmental problems affecting the quality of finished pile. In this paper,an engineering analysis of soil caused by pile driving horizontal displacement of the measured data obtained pile driving process,the horizontal displacement of soil with the pile driving area,depth and its rural character and larger variation of the difference. Research group piles of soil caused by the displacement of the paper introduces the overlay approach to simplify the estimate of the level of soil displacement and uplift displacement of pile groups is derived during the construction of soil displacement caused by the estimation formula,and with the works carried out experimental comparison,can be used for engineering.
