| 摘 要： | 通过在某沿海碎石土回填地基上成功实施的10000 kN.m高能级强夯系列试验,为10000 kN.m高能级强夯的设计、监测和检测提供了依据。本文根据对不同能级强夯后地基土平板载荷试验结果的分析与对比,得到了碎石场地强夯后P–S曲线为直线(缓降)型,其极限承载力和变形模量高,变形量小;夯点与夯间地基土的密实度基本一致;无需过大增加荷载板的面积等试验结果。

| Abstract: | A series of experiments of high energy dynamic compaction(DC) were successfully executed on a rubble filled site in a 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 detected results of plate loading test(PLT) were analyzed and compared with other DC with different energy levels.Some conclusions for rubble filled site after DC were acquired that the mild P-S curves indicated that the high bearing capacity and small deformation of foundation,the density of rubble at compacted drop points and between them was nearly equal,and it was not necessary to over-increase the area of loading plate. |
