不同能级强夯置换处理软土地基现场试验OA北大核心CSCDCSTPCD
Field Test of Dynamic Replacement Method on Soft Soil Foundation Under Different Energy-Levels
依托广西钦州港区某大型工程软土地基处理实践,开展8 000和15 000 kN·m能级强夯置换处理软土地基的现场试验;基于强夯置换过程中超孔隙水压力测试、强夯置换前后多道瞬态面波测试及重型动力触探试验、强夯置换后钻孔检测及静载试验结果,对地基承载力和土体工程特性变化进行详细分析.研究结果表明:2个能级强夯置换后,地基承载力均明显提高,土体工程特性得到改善,置换后复合地基承载力均大于200 kPa,变形模量分别大于20和15MPa,满足地基处理设计…查看全部>>
Based on foundation treatment practice of large-scale engineering in Qinzhou port,field test of dynamic replacement method on soft soil foundation under 8 000 and 15 000 kN · m energy-level was carried.Excess pore water pressure monitoring during replacement process,multichannel transient surface wave test and heavy dynamic penetration test before and after dynamic replacement,drilling test and static load test after dynamic replacement were finished in fiel…查看全部>>
