水泥混凝土路面的设计方法和参数

Dessign Method and Parameters of Cement Concrete Pavement

本文根据本刊上期《水泥混凝土路面板中应力分析》一文提供的理论基础提出了水泥混凝土路面的设计方法和计算参数。在设计方法中考虑了重复荷载应力和温度应力的综合疲劳作用。在计算参数方面,通过系统的现场实测和室内试验提供了地基模量值、混凝士强度参数、温度梯度值、接缝传荷能力系数、动荷系数和轮迹横向分布系数等数据。

According to the theoretical basis given in the paper 'Stress Analysis in Cement Concrete Pavement Slab' in last issue of this Journal, in this paper the design method and parameters for calculation of cement concrete pavement are presented. In the design method, the comprehensive fatigue effect of repcated load stress and temperature stress is cpnsidered. As to the parameters, through systematic field tests and laboratory experiments, the subgrade modulus, the strength parameter of concrete, the temperature gradient coefficient, the loadtransfering capacity coefficient of slab joint, the dynamic load coefficient and transversal distribution coefficient of wheel path are put forward.
