水工建筑物防渗系统沥青混凝土性能研究

通过分析沥青混凝土心墙防渗材料的特点和国内外研究现状,对沥青混凝土的制备要求和配比设计进行探讨.随后基于三轴试验,对沥青混凝土心墙进行研究,得出击实成型、静压成型实验结果,以及加载速率对沥青混凝土力学性能的影响.希望为今后水工建筑物沥青混凝土的配比和制备提供理论依据.

Study on Asphalt Concrete Performance of Seepage Control System in Hydraulic Structure

Asphalt concrete is the main material of seepage control system of hydraulic structure,especially widely used in earth dam core wall materials. With the increase of high dam,the safety stability of the core wall is crucial,so the asphalt concrete of hydraulic structure mechanics performance is imminent. Through the analysis of the characteristics of seepage control material in asphalt concrete core wall and the research status at home and abroad,all requirements for the preparation of asphalt concrete and the matching design were discussed. Then based on the triaxial test,the study on asphalt concrete core wall,static pressure molding experiments,as well as the loading rate and the hot and cold cycle on the mechanical behavior of asphalt concrete are analyzed respectively,which provide theoretical basis for asphalt concrete mix ratio in hydraulic structures.
