【摘要】 结合试验路段的实际情况 ,对无粘结预应力路面的受力情况荷载应力和温度应力作了详尽的分析。讨论了混凝土弹性模量、线胀缩系数、板底摩擦系数、地基回弹模量、温度梯度等一系列因素对路面应力的影响。分析计算所得的图表和结论可用于预应力混凝土路面的设计、施工更多还原

【Abstract】 In accordance with the actual condition of experimental road load stress and temperature stress which are important for unbounded prestressed concrete pavement(PCP) are analyzed in detail. The effect of a series of factors such as elastic modulus and linear coefficient of thermal expansion of concrete, friction coefficient of slab bottom, elastic modulus of subgrade, the percentage of lateral steel and temperature gradient on stress of pavement are discussed. The figures and relative analysis are of important reference value to the design and construction of PCP.更多还原
