毛乌素沙漠砂土地基处理效果分析
摘要:在对毛乌素沙漠南缘风积砂进行水坠砂(静水沉积和浸水饱和分层碾压)、振冲密实法(振冲砂桩)及强夯等现场试验的基础上,对不同地基处理方式后风积砂的物理特性和地基承载力进行了对比分析,提出了风积砂不同地基处理方式的优缺点,并对不同地基处理方式的机理进行了探讨。
Abstract:In the research, some field tests on different groud treatments of sand, including water-treatment (hydrostatic deposition process and Water saturated layered rolling process), vibroflotation and dynamic consolidation were carried out to aeolian sands Subgrade in southern fringe of Mu Us desert. According to these test data, this paper had analyzed the changes on physical characteristics and carried capacity of aeolian sand foundation under different ground treatments. Then it summarized the advantages and disadvantages of different ground treatments for aeolian sand foundation, and discussed the function mechanisms of different treatment methods.
