摘　　要：随着兰州地区工程建设向冲洪积盆地大规模的拓展,建设了各类基础形式、荷载较大的工程,冲洪积盆地粗颗粒土下卧粉土的地基岩土参数已成为工程设计人员关注的重点。该文通过试验与工程实践,分析了不同取样方法的室内试验与现场原位测试指标,并对兰州冲洪积盆地粗颗粒土下卧粉土层工程特性与地基参数进行了研究,对类似工程具有一定的借鉴意义。With the large-scale expansion of the engineering construction in Lanzhou to the alluvial proluvial basin, various foundation forms and projects with large loads are constructed. The foundation geotechnical parameters of the underlying silt of coarse-grained soil in the alluvial-proluvial basin have become the focus of the engineering designers. Through the experiments and engineering practice, this paper analyzes the indexes of indoor tests and field in-situ tests with different sampling methods, and analyzes the engineering characteristics and foundation parameters of the underlying silty soil layer of coarse-grained soil in Lanzhou alluvial-proluvial basin, which has reference significance for the similar engineerings.
