强夯法是一种经济高效的地基处理方法。对国内最大的黄土塬地区采用12 000kN.m高能级强夯加固湿陷性黄土地基的设计、施工、检测进行了系统全面的实践研究,通过探井取样与室内土工试验、静力触探试验、浅层平板载荷试验三种检测试验对高能级强夯处理后的地基进行综合检测,得到12 000kN.m高能级强夯的有效加固深度、消除湿陷性处理效果、提高承载力、降低压缩性等结论,为高能级强夯处理湿陷性黄土地基的设计、施工、检测提供一些有价值的参数和数据。
Dynamic compaction method is a cost-effective method of foundation treatment. A systematic and comprehensive study on the design, construction and testing of collapsible loess foundation with 12 000 kN.m high-level dynamic compaction is carried out on the largest loess plateau in China. Through sampling of exploration wells and indoor geotechnical tests, Shallow flat-panel load test Three kinds of test tests are carried out to comprehensively test the foundation after the high-level dynamic compaction treatment to obtain the effective reinforcement depth of the 12 000 kN.m high-level dynamic compaction, to eliminate the collapsible treatment effect, to improve the bearing capacity and to reduce the compressibility And other conclusions, provide some valuable parameters and data for the design, construction and testing of collapsible loess foundation with high-level dynamic compaction.
