【 摘 要 】

Relying on the test section of composite foundation with rigid-flexible and longshort piles in Xingheng expressway first phase project, the lime-soil compaction pile modified by steel slag was proposed to strengthen lake-phase soft soil with material properties analysis of steel slag. The modified characteristics, capacity and water resistance capability of the lime-soil compaction pile modified by steel slag were researched by series of mechanical tests. The construction effect and bearing capacity of lime-soil compaction pile modified by steel slag were evaluated by the static load tests and heavy dynamic penetration tests, which will provide technical reference for the further application of lime-soil compaction pile modified by steel slag.
