摘要： 在分析柔性路面的弯沉和应力时,采用了碎石层和土基层的材料非线弹性本构模型,以及碎石、土的非抗拉性能,编制了可以分析任意多层体系的路面结构的四边形单元非线弹性程序.给出了算例,与理论值和实测值进行比较,比较结果表明了本文理论和该程序的正确性.最后还作了进一步的工程应用.
关键词: 柔性路面, 有限元, 数值计算
Abstract: In this paper, computing deformation and stress of flexble pavement are analysed by non-linear FEM and nonlinear material constitution model of stone and soil is used, and non-ex tension of them is introduced.The computing program is designed and program med, which computes pavement structures of many different constitution models.A few exam ples are given, and the results show that this method is correct.
Key words: flexible pavement, FEM, numerial method
