摘要
灌注桩采用桩端压力灌浆新技术后,能大幅度地提高基桩承载能力,减小其沉降,在工程中已运用多年,但大量工程实践表明其对不同地层的适应性是不同的。根据某工程中钻孔灌注桩现场试验,对桩端压力灌浆技术在卵石层中灌注桩的运用效果其及经济、社会效益进行了分析。
The new pressure grouting technology under pile's tip has been introduced-to bored piles formany years. It can largely improve piles bearing capacity and reduce its settlement. A lot of engineering practice has indicated that its adaptability varied in different soil layer. Based on site tests, this paper discusses the effect of pressure grouting under pile's tip in gravel and analyzed its economic and social benefit.
