| 摘 要： | 通过在某沿海碎石土回填地基上成功实施的10000kN.m高能级强夯系列试验(3000,6000,8000,10000kN.m),为10000kN.m高能级强夯的的设计、监测和检测提供了依据。本文根据对不同能级强夯夯后地基的标准贯入试验分析与对比,得到了碎石土地基上10000kN.m强夯的有效加固深度等检测结果。建议若用于规范表格,对碎石土、砂土等粗粒土在10000kN.m强夯能级下的有效加固深度可取13～16m。

| Abstract: | A series of energy levels of dynamic compaction(DC)(3000 kN.m,6000 kN.m,8000 kN.m and 10000 kN.m) were successfully used in practice on a rubble fills site in coastal area for the first time in China.The experiment provided the parameters for the design,construction and detection of 10000 kN.m DC.The monitoring results of standard penetration test(SPT) were analyzed and compared with those of other energy levels.Some conclusions such as effective depth of improvement(EDI) on rubble fills site with 10000 kN.m DC were acquired.It was suggested that the EDI should take 13~16 m for gravel and sand,which might be uesd in the Table 6.2.1 of Ground Treatment Code of China. |
