摘　　要：对利比亚Sidi Alsaeh地区10 000套住宅项目强夯处理地基进行了标准贯入试验研究,并采用不同尺寸的方形承压板对强夯处理前、后挖方和填方区域地基进行浅层平板载荷试验,得出了标准贯入试验检测Sidi Alsaeh风积砂强夯处理地基是可行的。Sidi Alsaeh地区标准贯入试验锤击数与地基承载力存在相关性,通过浅层平板载荷试验确定的地基承载力与压板影响深度的标准贯入试验锤击数珚N的趋势性关系,确立了深层标准贯入试验锤击数N的检测标准。The standard penetration test did with the dynamic compaction ground treatment of the project named 10 000 sets of residential in the district Sidi Alsaeh,Libya. At the same time,the shallow plate load test was used to the excavation and fill area before and after dynamic compaction process used the different sizes square bearing plate. The experimental data shows that the wind-blown sand compaction ground treatment by the standard penetration test is feasible in Sidi Alsaeh. It found a correlation between the standard penetration test hammer number and the bearing strength of the ground in Sidi Alsaeh area.According to trend relationship of the foundation bearing capacity by the shallow plate loading test determined and the platen impacting depth of the standard penetration test hammer number 珚N,it can be established the test standard of the deep standard penetration test hammer number N.
