摘要
在分析片石混凝土材料特性的基础上,用三维有限元软件COSMOS对片石混凝土路面荷载应力进行计算,同时采用正交设计方法对荷载应力的影响因素进行分析,得出各影响参数的变化规律,并采用均匀设计法安排参数组合,SPSS回归分析软件拟合出适用于片石混凝土路面荷载应力的实用计算公式。
On the basis of analyzing the characteristics of industrial rubble concrete materials, the load stress of industrial rubble concrete pavement surface is calculated by means of 3-D finite element software COSMOS. At the same time, the or- thogonal design method is used to analyze the factors influencing the load stress, and the variation rule of influencing pa- rameters is obtained. The uniform design method is adopted to arrange parameters combination ; and a practical computation formula that can be applicable to the load stress calculation for rubble concrete pavement is worked out by SPSS regression analysis software.
