利比亚Sidi Alsaeh地区大面积风积砂丘地基的场地条件、地基状况、强夯加固、效果检验等方面的研究和工程实践表明,在大面积风积砂丘地基采用强夯加固处理是可行的;由于场地平整后的地基承载力差异较大,为满足承载力、沉降控制及地基均匀性要求,采用统一的高夯击能和夯击次数效果不显著,对不同工况地基宜选用不同的强夯处理参数;SidiAlsaeh地区风积砂场地地基承载力与标准贯入击数之间符合趋势性统计关系,缺乏严格对应关系,效果检验应选用标准贯入试验与静载试验对照进行。
The research and engineering practice of large area aeolian sand ground in Sidi Alsaeh area of Libya, such as site conditions, foundation conditions, dynamic compaction, effect test and so on, show that it is feasible to apply dynamic compaction to the foundation of large area aeolian sand hill. In order to meet the requirements of bearing capacity, settlement control and foundation uniformity, the effect of uniform high impact energy and number of tamping is not significant. For different conditions, it is appropriate to choose different dynamic consolidation methods Parameter; the relationship between the bearing capacity of foundation and the number of standard penetration strikes in wind-blown sand ground in SidiAlsaeh area is in accordance with the trend statistical relationship, lack of strict corresponding relationship, and the effect test should be conducted by standard penetration test and static load test.
