Abstract

Abstract: There are generally three types of overlays of repaving new cement concrete pavement on the old one, such as combined-form overlays, split-overlays and direct overlays. This paper integrates traditional mechanics with fracture mechanics, analyzes the separating process and its influence on overlays and old pavement in the combined-form pavement structure, and explores the influence of combined-form pavement overlays on mechanics properties caused by the crack in the old pavement by finite-elem

Key words: cement concrete overlays, combined-form, fracture mechanics, crack, finite element

摘要： 旧水泥砼路面上加铺新水泥砼补强层，一般可采用3种加铺层型式：结合式、分离式和直接式．本文结合传统力学和断裂力学原理，对结合式加铺层路面结构中加铺层与旧面层的界面分离过程及其影响进行了分析；借助有限元计算手段，分析了旧砼路面板中的裂缝对结合式加铺层路面结构力学性能的影响
