摘　　要：为了深入分析半刚性基层沥青路面反射裂缝的破坏机理,文章运用有限拆分软件建立计算模型,在车辆正载和偏载作用下,分析含LSPM层的典型复合基层路面结构内沥青面层层底的力学响应,并比较半刚性基层开裂前后面层层底在裂缝尖端区域应力场的变化,以期为工程应用提供理论依据.In order to analysis the reflective crack destruction of semi-rigid base asphalt pavement , the paper apply FLAC to build up the computer model , Under the vehicle normal load and partial load , analysis the mechanical response of bottom of the asphalt surface level , that is typical composite basic level pavement structure contain LSPM level.And compare with the stress field＆#39;s change at the crack tip area , it is bottom of the surface level bed , before and after of semi-rigid base crack .Expect to provide theoretical basis for engineering application .
