地基处理中预制桩的选型试验

THE OPTION OF PRECAST PILE FOR FOUNDATION TREATMENT

通过对预制方桩和管桩的比对试验,得出两种桩型的竖向承载能力差异较小,单桩水平临界荷载和极限荷载存在很大的差异,通过比对试验给出了两种桩型的承载能力及地基土水平抗力系数的比例系数m值,分析两种桩型之间存在的差异的原因。建议地基处理工程中应优先选择预制管桩。

This article discusses the test comparisons of the precast square piles and pipe piles,the bearing capacity and 'm' value is proposed,the vertical bearing capacity shows little difference,but the horizontal bearing capacity shows much difference,the cause of difference between the precast square piles and pipe piles is analysed.It is suggest that the precast pipe piles should be selected and put to use in similar foundation treatment project.
