摘　　要：为探索尺寸效应对于沥青混凝土心墙性能的影响,文章在沥青混凝土小梁弯曲试验规程试验原理基础上,研制出沥青混凝土大梁弯曲试验原型机,钻研得到沥青混凝土大梁弯曲试件的成型方法,并且探索出将现有沥青混凝土小梁弯曲试件尺寸放大10倍的水工沥青混凝土大梁弯曲试验方法,最大限度地减小尺寸效应对于沥青混凝土弯曲性能的影响。本成果填补了水工沥青混凝土原型试验领域的空白,为水工沥青混凝土尺寸效应的研究提供了依据。In order to investigate the influence of size effect on the performance of asphalt concrete core walls,this study,based on the testing principles of the asphalt concrete small beam bending test outlined developed a prototype machine for bending tests of hydraulic asphalt concrete large beams.The study also devised a method for fabricating asphalt concrete large beam specimens and established a testing method by scaling up the size of existing asphalt concrete small beam specimens by a factor of 10.This approach minimizes the impact of size effect on the bending performance of asphalt concrete to the greatest extent possible.The results fill a gap in the field of prototype testing for hydraulic asphalt concrete and provide a basis for further research on the size effect in hydraulic asphalt concrete.
