摘要
根据沥青路面结构可靠度的含义及的几何意义,将可靠度的问题就转化为求解有约束条件的极小值问题后,采用PSO求解可靠度指标优化模型,成功地将PSO应用于沥青路面结构可靠度计算领域,进一步丰富了沥青路面结构可靠度的分析计算理论。
Based on the meaning of confidence level for the asphalt pavement structure and the geometry meaning of (,and after the problem of confidence level is translated to find the solution for the inhibiting condition of the minimum,PSO is used to find the solution of the confidence level index optimizing model. PSO is successfully applied to the calculation field of the confidence level for asphalt pavement structure,which is further affluent in the analysis calculation theory of the confidence level for the asphalt pavement structure.
