英文摘要	Settlement deformation control of loess high fill is the key and difficult point in engineering construction. In this paper, the deformation characteristics of remolded loess under self-weight stress and water content change are summarized by indoor lateral confined compression test and humidification test. Based on the idea of layered summation method, the Gunary stress-strain model and secant modulus method are introduced to divide the settlement of loess high fill foundation into the settlement during construction caused by loading and the settlement after construction caused by water content change, and the calculation method of settlement deformation of loess high fill foundation is put forward. Combined with the actual engineering background, the settlement deformation of high fill engineering is predicted. The results show that the main source of the settlement of high loess fill is the settlement caused by the loading during the construction period. With the increase of fill height, the proportion of post-construction settlement to total settlement increases gradually. Under the condition of optimum moisture content, the exhaust consolidation of soil can be completed when the compaction degree during the construction period reaches more than 95 %, and the later stage of construction is the drainage consolidation of soil. The control of compactness is crucial to high fill engineering. The higher the compactness, the smaller the total settlement. The research results of this paper enrich the calculation theory of settlement deformation of loess high fill foundation, and provide theoretical basis for the study of post-construction settlement and collapsible settlement of loess high fill; it has certain reference value for the construction and post-construction settlement control of loess high fill engineering.
