| 摘 要： | 对内蒙沙漠土进行8 000 kNm、6 000 kNm、4 000 kNm、3 000 kNm能级强夯法地基处理试验,通过标准贯入试验、动力触探试验和平板载荷试验对强夯后的沙漠土进行检测,得出各种能级强夯对沙漠地区填方区、挖方区处理后的有效加固深度和承载力.对强夯法处理沙漠土的一些规律进行总结,给出各种强夯能级能够处理的有效加固深度、夯点间距等设计施工参数,供类似地质条件下强夯地基处理工程借鉴参考.

| Abstract: | The dynamic compaction tests with 8 000 kNm, 6 000 kNm, 4 000 kNm and 3 000 kNm energy-levels for treating desert soil in Inner Mongolia were carried out. And then through the standard penetration test, cone penetration test and the static plate loading test on the desert soil after dynamic compaction, for different levels of dynamic compaction of the desert area of fill areas, excavation zone after reinforcing, the respective effective treatment depths and bearing capacities of reinforcement are obtained. Some rules of dynamic compaction treatment on the desert soil are summarized; some construction parameters of dynamic energy level, effective reinforcement depth, spacing, etc. are given, so as to offer for reference in the similar geological conditions for the foundation treatment works with dynamic compaction. |
