摘要

以连续配筋混凝土路面（CRCP）近年来应用比较广泛的路面结构形式为研究对象，采用考虑地基压缩系数和水平剪切系数的双参数地基模型，建立了考虑地基土体滞回阻尼的黏弹性地基上CRCP的振动微分方程，运用三角级数和Fourier变换得到了简谐、矩形均布荷载作用下路面竖向位移的解答，并利用Fourier逆变换得到了数值结果，较为全面的分析了荷载速度、频率、路面配筋率、板厚以及地基参数对板的动力响应的影响。研究结果可为路面动力响应分析及连续配筋混凝土路面的质量评价提供参考。

Abstract

The dynamic displacement response of continuously reinforced concrete pavement(CRCP)

which has horizontal resistance at its bottom

resting on a viscoelastic foundation has been investigated when the system is subjected to a harmonic moving load. The vertical displacement expressions of CRCP are obtained by using the trigonometric series and the Fourier transform when hysteretic damping is considered. Numerical results are derived through the inverse fast Fourier transform method(IFFT) and used to analyze the influence of various parameters such as the load velocity

frequency

reinforced ratio

strip thickness and foundation parameters on the dynamic displacement responses. The results can be for reference in analysis of dynamic response and pavement evaluation of CRCP.
