| 摘 要： | 以洛阳华润热电新建电厂工程为背景,开展了湿陷性黄土的强夯试验,探讨了强夯处理黄土湿陷性的效果.同时建立强夯的三维动力分析有限元模型,对黄土强夯效果的影响因素进行了分析.分析结果表明:采用强夯工法能很好地消除黄土的湿陷性;强夯能级越大,强夯的径向影响范围和竖向影响深度越大;在处理深厚湿陷性黄土时,相同能级条件下宜采用半径较小的夯锤.

| Abstract: | In this paper,the compaction tests for collapsible loess were conducted and the improvement effect of compaction was discussed in Huarun power plant at Luoyang. Finally,the influence factors of compaction was analyzed based on 3D dynamic FEM model. The analysis results show that：the collapsible of loess is eliminated by compaction primely;the higher the compaction energy is,the larger the radial and vertical influence area is;under the same compaction energy,the hammer with smaller radius is more suitable in the treatment of deep collapsible loess. |
