分析了水泥混凝土路面路面板翘曲变形处理为2组垂直交叉地基梁翘曲变形叠合的威氏方法的适用性和精度,总结了半无限地基和半刚性基层上路面板的温度翘曲应力变化规律,通过引入等效梁长和当量相对梁长2个概念,提出了半无限地基板任一点、计入半刚性基层超宽影响的梁中点的翘曲应力公式。
The applicability and precision of the Vickers method for the warpage of cement-concrete pavement pavement slabs are analyzed. The warping stress changes of the pavement slabs on semi-infinite foundation and semi-rigid base are summarized By introducing two concepts of equivalent beam length and equivalent relative beam length, a warping stress formula for mid-point of beam with semi-rigid base layer is included in the calculation.
