按现行水泥混凝土路面设计方法(弹性地基上无限大板解析介),进行荷载应力计算时,只能求算板中应力,当荷载作用在板的边缘或角偶时,弹性半空间体地基上板所受弯矩或应力的分析问题,在理论上没有得到解决。尤其对多轴,多轮的平板挂车,作用于混凝土板上时,应用现行方法进行荷载应力的分析,更会产生不少困难,且难以得到合适的结果。目前,广泛应用的有限元法,可将混凝土板划分为有限个单元。多轴、多轮荷载同
According to the current design method of cement concrete pavement (infinite plate analysis on elastic foundation), the stress in the plate can only be calculated when calculating the load stress. When the load acts on the edge or angle of the plate, the foundation of the elastic half-space body The bending moment or stress analysis of the plate has not been solved theoretically. Especially for multi-axis, multi-wheel flat trailer, acting on the concrete slab, the application of the current method of load stress analysis, it will have many difficulties, and difficult to get the appropriate results. At present, the widely used finite element method, the concrete slab can be divided into a finite number of units. Multi-axis, multi-wheel load with
