摘要
首先根据混凝土材料组成的微观颗粒结构 ,利用分形几何学的基本原理对水泥混凝土路面裂缝分布进行描述 ,对混凝土弹性模量、配合比和分维数对水泥混凝土路面性能的影响进行了研究和分析 .然后建立水泥混凝土路面裂缝形成机制的键渗流模型 ,应用重正化群理论计算渗流阈值 ,并由此确定混凝土路面的破坏条件 .最后分析了分形。
Based on the microcosmic structure of the concrete and with the help of the principle of fractal geometry, the paper first describes the distributing cracks, and analyzes the relationships between elastic module of concrete pavement and fractal-dimension, composing ratio of concrete and Fractal-dimension. Then Bond-seepage model of forming mechanism of cement concrete cracks is set up and the clique value is obtained by using renormalization in order to understand the wrecking conditions of concrete pavement. At last, the paper discusses the relationship among fractal geometry, clique value, and the performance and wrecking conditions of cement concrete pavement.
