| 摘 要： | 通过试验测定了三明高速公路典型高液限土样在不同含水率情况下的重型击实密度、泡水前后的强度和水稳性;分析了土样干密度、密实度、浸水CBR强度与含水量之间的关系.试验结果表明:在含水率为25%～32%范围内进行该高液限土路基的填筑压实,可以取得较高的路基强度和水稳定性;综合考虑路基的压实度和浸水CBR强度,三明高液限土在93区填筑的质量控制标准为含水率介于25%～30%之间,压实度≥93%.

| Abstract: | Through laboratory tests,dry density under heavy compaction,strength before and after soaking,water stability of typical high liquid limit soil sample from expressway engineering in Sanming under different water content are measured.The relationships between dry density,degree of compaction,CBR strength after soaking and water content of the sample are also analyzed.The compaction standards of high liquid limit soil highway subgrade with CBR soaked strength and compaction degree are put forward. |
