| 摘 要： | 由于各种因素的影响,碎石桩处理液化粉土地基的挤密效果与设计计算结果在某些情况下会有较大的差别。本文通过某高速公路试验路段的实测资料,分析和总结了影响碎石桩挤密效果的六方面的影响因素,并在此基础上提出了一种可以考虑碎石桩置换率、粉土黏粒含量和土层埋深的新的设计方法,并通过工程资料验证了该方法的合理性。

| Abstract: | It is known that there are many factors affecting the compaction effect of grav el composite piles,especially in silt ground.Six factors were studied in this paper by analyzing the testing data from five testing areas of a highway project in China and a new design method is proposed,which is capable of consi dering the influence of clay content and buried depth on compaction.This design method is also proved being feasible by the test data from some projects in China. |
