Abstract: In this paper,through static penetration and standard penetration,we got the data of using sand compaction pile for soft soil treatment and tested the sand pile & the soil among piles of soil treatment.By analysizing statistics,we establisheol the relationships between the two testing methods and worked out the limit tatum to sure the density of sand compaction pile.We have found a quick and practical test method to use static penetration to examine the construction quality of sand compaction pile and to speed up the construction of soft soil treatment and the density examing of sand pile by supervisors.

Key words: static cone penetration, standard penetration, sand pile

摘要： 通过静力触探与标准贯入两种试验方法，测试处理软基的砂桩与桩间土，获得了挤密砂桩处理软土地基的试验资料．通过统计分析，建立了两种测试方法的相关关系，提出了判断挤密砂桩密实程度的界定值．为采用静力触探快速检测砂桩施工质量，加快软基处理的施工进度与监理工程师确认砂桩的密实度，找到了一种快速可行的检测方法．
