A good model of the full - grade aggregate concrete with high aggregate content is precondition to successfully execute concrete meso - mechanical simulation, so that the main work in the dissertation is focused on the following study concerning the random aggregate model of dam fully - graded concrete : ( 1 ) based on the topology of spherical aggregates, an algorithm of the random convex polyhedron aggregate model was presented considering the actual aggregate content, grading, and aggregate shape, and corresponding fortran program was developed to generate random convex polyhedron aggregate
針對全級配大壩混凝土的實際骨料含量和骨料形態，本文做了以下主要工作: （ 1 ）在一種高效率生成的隨機球骨料模型的基礎上，形成隨機凸多面體骨料模型，同時研究了細觀單元屬性判別方法，編制了對含有凸多面體骨料的細觀區域進行結構性有限元網格剖分程序。本文給出的三維隨機骨料模型演算法不但考慮了混凝土的骨料的實際級配和含量，而且計及了骨料的實際形態。 -
Based on the chang - yu highway in julin province, this paper focus on gap - graded asphalt mixtures. aggregate grading of the gap - graded hma was designed by means of void design procedure. this paper give out a kind of new gradation of stone matrix asphalt. at the same time, this paper also studies the effect of aggregate size on road - related performance in some different gradings
本文以吉林省長余高速公路為依託，從瀝青混合料的結構形態入手，利用體積法，對骨架密實型級配類型的瀝青混合料的級配進行研究，提出新型的瀝青馬蹄脂級配，並針對不同級配的瀝青馬蹄脂碎石混合料，全面分析了粗，細集料的粒徑變化對其各種路用性能的影響。 -
