东亚大厦强击沉管灌注桩施工对邻桩的影响

Influence of Heavy Hammered Pipe Pile Construction of Dongya Building On the Adjacent Ones

强击沉管灌注桩在淤泥地区中施工，对邻桩有较大的影响，需确定合理的“跳桩”时间．试验证明，在淤泥地区进行强击式沉管灌注桩施工，设计桩距小于２．５倍桩径时，应在邻桩灌注混凝土初凝期后才能施工．本文对一般沉管灌注桩施工．亦有参考价值．

he construction of heavy hammered pipe pile in muck is of influence on the adjacent ones to a greet extent,so the interval. It is shown by tewt that the heavy hammered pipe pile should be constructed only after initial cementing period of concrere of adjacent ones when the pile spacing is less then 2 meters. The test results are of certain reference signaficance for the construction of ordinary heavy hammered pipe pile.
