摘　　要：针对采煤回填区条件下的湿陷性黄土地基处理问题,以榆林市府谷县内农光互补项目升压站地基处理为例,通过现场和室内相结合的方法开展静荷载、标准贯入、土工及压实度试验,分析了强夯处理施工工艺对采煤回填区地基承载力、土壤密实度和土壤湿陷性影响。结果表明:强夯处理施工技术能有效提升地基承载力、增大了地基土壤密实度和土壤均匀性、消除了土壤湿陷性。研究结果可为采煤回填区湿陷性黄土地区的工程地基处理提供技术参考。The treatment of collapsible loess foundation in coal mining backfill areas is studied.Taking the booster station foundation treatment work of the agriculture and photovoltaic complementary project in Fugu County,Yulin City as an example,in-situ and laboratory experiments are carried out,including static load,standard penetration,geotechnical and compaction tests.The influences of dynamic compaction treatment on the foundation bearing capacity,soil compactness,and soil collapsibility in coal mining backfill areas are analyzed.The results show that the dynamic compaction treatment technology can effectively improve the foundation bearing capacity,increase the compactness of the foundation soil,and eliminate the soil collapsibility.It provides useful technical reference for the collapsible loess foundation treatment in coal mining backfill areas.
