Tamped and Expanded pile is a simple, economical and effective method to deal with collapsible loess foundation,and has been widely used in the engineering works. Finally, the computer simulation software ADINA is adopted to do single-pile and multi-pile numerical simulation on the composite foundation, internal forces’ transferring law along the pile’s depth and soil pressure’ distribution along pile radial direction as well as change law of the pile’s settlement are analyzed. Meanwhile, stress ratio of pile to soil is also studied, and the conclusion is drawn that the effective reinforcement range of Tamped and Expanded pile is 6 to 10 d, the earth pressure is in a Bell-shaped distribution along radial direction of pile, and pile’s settlement mainly concentrates in the scope of 1 ~ 1.5 d and so on, all of which have guiding significance for the design and construction of Tamped and Expanded piles. 小四号Times New Roman字体，20磅行距、首行缩进2字符，两边对齐 小四号Times New Roman字体加粗，上空两行，左对齐。 Keywords: collapsible loess, Tamped and Expanded pile, Compaction Effects, simulating calculation小四号Times New Roman字体 石家庄铁道大学毕业设计  PAGE 6 重新起一页 二级目录 一级目录 目 录小三号黑体、20磅行距、段前后30磅、居中，设置为1级标题 … TOC \o 1-3 \h \z \u  三级目录  HYPERLINK \l _Toc186535683 第1章 绪 论  PAGEREF _Toc186535683 \h 1  HYPERLINK \l _Toc1865356
