湖区淤积土冲击沉管灌注桩桩身缩颈成因及对策

The reason and countermeasures for the pouring stake's shorten of the vibration sinking tube in deposite swamps earth

分析了湖区淤积土振动沉管灌注桩桩身缩颈的成因,通过理论计算、接合实际施工特点,提出了避免桩身出现缩颈的施工对策和施工方法,可供相关工程作为参考。

The reason for the pouring stake＇s shorten of the vibration sinking tube in the deposite swamp earth was analyzed in the paper. Basing on the charccterstics of the practical operation , the countermeasure and technology were oppointed with the theoretical calculation, which could be suspected as the references for the related projects.
