| 摘 要： | 将已有的沉桩挤土变分理论解答应用于室内模拟压桩验证计算与分析。结果表明,理论计算与模型试验测试数据、数值计算结果吻合得较好,而桩土作用的变分解答和模拟压桩实测结果之间的主要误差是由扩张模型假设条件引起的。研究成果可以提高应用理论计算方法定量分析解决实际问题的能力,并提高压桩模拟试验设计水平。

| Abstract: | The computing and analysis are carried out for a pile-jacked experiment with the already obtained theoretical solutions for soil squeezing effect.Comparison between the test data and computing results shows that theoretical solutions and calculating progress are reasonable and the differences come mainly from the pile expansion model.The research is to promote the application of theoretical calculation method for the quantitative analysis and to solve practical problems of design level of piling simulation test. |
