摘要
对粉质土地基中水冲沉板桩进行了单桩静力载荷试验,试验数据表明承载力为预制桩规范估算值的16%～20%。在采取水泥返浆进行桩土固结后,竖向承载力将提高,达到预制桩规范估算值的22%～27%。
This paper introduces the test on the individual pile bearing capacity of outwast pale in powder earth foundation.The test data shows that the bearing capacity values 16%～20% of the promoulded pile specification evaluation.After consolidating on the pile earth with adopting backgrouting,the bearing capacity is improved and it reaches to the 22%～28% of the promoulded pile specification evaluation value.
