钻孔压浆桩是近几年发展起来的一种新型桩,它具有适应土层范围宽、施工速度快、噪音小、无泥浆污染、桩身质量好和承载力较高等优点,因此越来越受到工程界的青睐。为了提高地基承载力,某电厂二期工程采用了大量的钻孔压浆桩。为了探索钻孔压浆桩在该地基中合理的施工工艺、参数,在工程桩正式施工前先制做了试验桩,并用静载试验法对单桩承载力进 Drilling grouting pile is a new type of pile developed in recent years. It has the advantages of wide range of application, fast construction speed, low noise, no mud pollution, good pile quality and high bearing capacity, The more the engineering sector of all ages. In order to improve the bearing capacity of foundation, a large number of drilling grouting piles were used in the second phase of a power plant. In order to explore the reasonable construction technology and parameters of drilling grouting pile in this foundation, the pilot pile was made before the construction of the engineering pile and the static load test method was used to calculate the bearing capacity of the pile
