摘要
依托广西南宁某公路路基工程,采用轻型动力触探击数N10对回填土强度参数测试进行分析。结果表明,针对固结程度好、回填时间长的回填土,采用轻探动力触探击数N10对回填土强度参数进行评价具备可靠效果;理论锤击数变化趋势和轻型动力触探击数N10变化趋势整体保持一致。该方法在天然回填土地基承载力检测中的应用效果良好。
Based on a highway subgrade project in Nanning,Guangxi Province,the light dynamic sounding number Nio is used to test the strength parameters of backfll soil.The results show that for the backfil with good consolidation degree and long backfill time,it is reliable to evaluate the strength parameters of the backfill by using the light probe number Nio.The variation trend of theoretical hammer number is consistent with that oflight dynamic sounding number Nio.The application of this technology in the bearing capacity test of natural backfill soil foundation is good.
