摘要: 为了研究软土中水泥土群桩的工作性能和承载力等问题,进行了系统的现场足尺试验。通过埋设测试元件对承台土反力、桩身轴力及复合地基变形等进行了量测。根据部分试验结果系统地分析了单桩、四桩、九桩情况下,桩长、置换率、桩数等关键参数对复合地基的承载力及变形模量的影响。

Abstract: The systematic full scale tests in situ were carried out to determine the behaviour, function and bearing capacity of cement stabilized soil pile composite foundation in soft soil. The pressure under cap,axis force along pile and deformation of foundation were obtained from these tests. The bearing capacity and deformation of fourpile and ninepile composite foundation were systematically analyzed based on part of the test results.The influences of length,spacing and number at pile on bearing capacity and deformation module of cement stabilized soil pile composite foundation are studied.
