摘要
对黄土塬某工程的湿陷性黄土地基采用15 000 kN.m高能级强夯加固处理。通过探井取样与室内土工试验、静力触探试验、浅层平板载荷试验3种方法对强夯处理效果进行综合检测和研究,得出15 000 kN.m高能级强夯加固湿陷性黄土地基的有效加固深度。试验表明,强夯处理后消除湿陷性效果显著,地基土承载力明显提高。
15 000kN.m high energy level dynamic compaction is used to improve collapsible loess foundation of some project in loess tableland area.Based on the sampling wells and laboratory soil test,cone penetration test and shallow plate loading test,the effective reinforcement depth of collapsible loess foundation is improved with 15 000kN.m high energy level dynamic compaction.The tests indicate that the effect of compaction variables is remakable and soils bearing capacity is improved obviously.
