| 摘 要： | 素土桩挤密地基由桩间挤密土和回填素土夯实的桩体组成，它是一种人工“复合地基”。其作用是通过素土桩挤密法提高地基土的密实度，从而对湿陷性黄土达到消除浅部或深部的部分或全部湿陷性的作用，并改善地基承载能力，减少地基变形。本文通过现场单桩、群桩单元体轻便触探、小环刀深层取样、开剖取样等方法对场地地基土挤密前、后干重度和压实系数进行了对比分析，判定用素土桩挤密法处理陇东湿陷性黄土地基的可行性。

| Abstract: | The extrusion foundation by usually soil piles consists of extrusion soil between the piles and pounded backfill piles,and is a artificial compound foundation. Its action is raised the density of foundation soil by means of extrusion of usually soil piles thus reach partly or wholely to remove the loess damp-settlement,and increase the load-beraing capacity of the foundation and decrease a foundation deformation. This paper was analysed and contrasted the dry weight and the compressibillity before and later extrusion of foundation soil in the site by means of lighe touch-probe, deep sampling by means round knife and sampling by a cut open, and was judges a possibility to treat a damp-settlement of loessial foundation with usually soil piles extrusion method. |
