用碎石桩防止粉土地基液化的设计方法

在讨论现有的用挤密砂石桩防止破土地基液化以及用挤密砂桩防止份土地基液化的设计方法的基础上，进一步提出了一个考虑细颗粒含量影响的挤密碎石桩防止份土地基液化的设计方法．通过对７组工程实测资料进行分析，初步显示出该方法的可行性。

A DESIGNING METHOD OF GRAVEL COMPACTION PILE AS A COUNTERMEASURES AGAINST LIQUEFACTION

On the basis of discussing the ues of gravedand sands compaction piles to prevent the liquefactions of sands and silt,the paper gives a design method of using gravel compaction piles to prevent silt liquefaction, in which the affect of fine content is consideed. By analysing the testing data from 7 engineerings, the method is proved to be feasible.
