摘要
根据高速公路工程液化地基加固试验研究,对干振碎石桩加固液化地基的原理、设计和施工参数进行了探讨,通过地基处理前后桩间土物理力学性质、标准贯入试验、静力触弹试验等测试结果的对比分析,表明干振碎石桩用于处理液化地基具有较大的优越性,值得推广应用。
Based upon experimental study on reinforcement of liquefiable foundation in expressway works and introduction of working principle of dry-vibrated gravel pile practical design and construction are introduced.Results of standard penetration test and static cone penetration test and physical and mechanical properties of soil among pile are comparatively analyzed.Practice shows this method is superior in liquefiable foundation treatment.
