摘　　要：将已有的压桩挤土变分理论解答应用于现场压桩挤土计算.分析表明,计算结果与现场压桩监测数据吻合的较好,而桩孔扩张的变分解答和现场压桩实测结果之间的主要误差是由扩张模型引起的.The theoretical computing and analysis are carried out for a pile with the already obtained theoretical solutions for soil squeezing effect due to in-situ pile jacked. Comparison between the monitoring data and computing results shows that the method and calculating progress are reasonable and the difference mainly comes from partial unreasonable of pile expansion model. The study is important for sorting out to deal with engineering problems and increasing economic benefit of it.

关 键 词：变分解答 桩孔扩张 扩张模型
