解釋
全級配骨料-
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。
