| 摘 要： | 为了评价共振密实法加固可液化地基的效果,对宿(迁)新(沂)高速公路某15m厚粉土地基场地采用可变频振动桩锤和自行研制的十字形振动杆进行处理,并进行孔压静力触探(CP-TU)测试.在应用CPTU测试进行液化判别的基础上,利用分析得到的相对密实度、有效内摩擦角和压缩模量等场地土性参数和抗液化性能变化对处理效果进行定量评价,...

| Abstract: | In order to investigate the densification effects of resonance compaction on liquefiable sites,deep vibratory compaction equipment with frequency-variable piling vibrator was adopted to insert a self-developed probe of crisscross section into the 15 m thick silt deposit at Suqian-Xinyi Expressway to treat liquefiable site and in situ piezocone penetration tests(CPTU) were performed before and after soil densification.The research results of liquefaction analysis based on CPTU were reviewed,and soil paramete... |
