摘　　要：通过对大渡河长河坝水电站野坝移民安置场地地基土特性的研究分析,并横向类比多个同类型粗粒土回填垫高区移民安置场地,总结出粗粒回填土场地地基土岩土工程特征,提出了回填块碎石土物理力学参数建议值,并给出了地基基础形式的建议,对其它类似工程起到了一定的借鉴作用。Based on the research and analysis of the subsoil characteristics of the resettlement site of the Yeba of Changheba hydropower Station in Dadu River,the geotechnical engineering characteristics of the subsoil of the subsoil of the coarse-grained backfill site are summarized by horizontal analogy with the resettlement sites of the same type of coarse-grained backfill high area.This paper puts forward the suggested values of the physical and mechanical parameters of the backfill gravel soil,and gives the suggestions of the foundation form,which can be used as a reference for other similar projects.
