摘要
结合工程实际，探讨了水泥土桩复合地基承载力标准值的取值方法，研究了垫层厚度对复合地基承载力及桩土应力比的影响，分析了几种常用水泥土桩承载力的评价方法所存在的问题，提出了标准贯入试验法，认为该法是评定水泥土桩承载力较可靠的方法，同时根据大量工程实测资料统计分析，给出了水泥土桩７ ｄ 和２８ ｄ 龄期无侧限抗压强度与水泥土桩身标准贯入击数Ｎ 值的经验关系，具有工程应用价值．
Based on the test results of projects, this paper analyses several problems of the cement soil pile composite foundation, including the way of getting the value from loading test P S curve, cushion effect, the choose of the design parameter and the evaluation of pile capacity. Some good results are put forward.
