摘要
本文根据港区道路堆场水泥混凝土铺面的荷载特点和使用要求,采用win-bler地基上Reissner厚板模型计算铺面结构的荷载应力,并同时考虑了铺面结构层内的温度应力影响,板间接缝传荷效应,荷载的动态效应,混凝土抗弯拉强度的后期增长效应,以及结构参数不定性的影响,建立了以疲劳损坏和一次性极限破坏为损坏标准的港区水泥混凝土铺面结构的设计方法.
Based on the characteristics of loads and the service requirement of cement concrete pavement of road and terminals in port areas, the author developed a new concrete pavement structure design procedure taking the fatigue cracking and limit failure as design criterion. In this design procedure , the load stress is calculated by use of the Reissner theory of thick slab on Winkler foundation, and the effect of thermal stress in pavement layers, load transfer effect between joints of slabs, dynamic effect of load, growth of concrete flextural strength in late stage and the indeter-minateness of structureal parameters are considered.
