摘要
介绍了自扩式沉管灌注桩的扩底施工新技术,并结合静载试验与普通沉管灌注桩进行了比较,分析表明该桩型具有高承载力、低沉降量的显著特点,而且施工相当简便,经济效益好,具有广阔的应用前景。
In this article,authors introduce the new bottom\|enlarging construction technology of self\|enlarging sunk pipe grouting piles,analyze its working principle,and compare them with common sunk pipe grouting piles combining with static load experiment.The analysis result indicates that this pile type has advantages such as high bearing capacity,little sedimentation,simple construction and good economic benefit,and has an extensive application prospect.
