摘要
针对机场混凝土道面板不同尺寸、不同边界效应的破坏模式预测问题,提出了一种预测道面板开裂模式的细胞自动机方法.该方法通过所选取的传递函数来描述道板边界约束对局部区域的效应,计算出的道板局部区域状态值形成道板构造状态数值模式.用最小误差原理建立起的类似区域匹配准则计算基础道板和新道板之间的类似区域.将基础板开裂特征值投射到新板的类似区域,图构出新道板的开裂模式.算例验证了方法的可行性.该方法可以直接基于实测数据精细预测混凝土跑道开裂模式.
This paper puts forward a cellular automata （CA） technique in order to predict the cracking patterns of concrete slabs with different sizes and boundary types. The CA technique describes the effect of boundary con？straints on the local zones within a slab, through the selected transition function. The CA state values of local zones calculated by the transition function form the state value mode of the slab. The minimum error principle was used as the criterion of zone similarity within and between slabs. Through the criterion for projecting cracking characteristic values from the base slab to the similar area of the new slab, the cracking pattern of the new slab was mapped. The case studies verify the validity of the CA technique. The developed CA method realizes the precise prediction of cracking patterns of concrete pavements based the tested data.
