Experimental Study on Effective Reinforcement Depth of Collapsible Loess Foundation Improved with 15000kN·m High Energy Level Dynamic Compaction

Tang Kesheng1,Guo Wei2(1.Gang’an Construction Co.,Ltd.,Qingdao Port Group,Qingdao,Shandong 265500,China;2.Shanghai Harbor Quality Control & Testing Co.,Ltd.,Shanghai 200032,China)  
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.
