摘要
阐述沥青路面水损坏机理,介绍ABAQUS有限元仿真软件,利用ABAQUS非线性动态分析能力建立了沥青路面渗流场、应力场三维有限元数值模型,对孔隙水压力、三向应力及竖向沉降的发生及变化规律进行探讨,并在某高速公路上建立试验段进行试验验证。由算例分析可知,用ABAQUS有限元软件模拟沥青路面降雨条件下的渗流场及移动荷载下的应力场是可行的,效果良好。
The seepage damage mechanism is explained, and the finite element simulation software ABAQUS is introduced in the paper. The seepage field and stress field 3D finite element numerical model of asphalt pavement are established by using the nonlinear dynamic analyzing ability of ABAQUS. The occurrence and changing regularity of the pore water pressure, vertical displacement and 3D stress are explored. Then the test on simulate road of one highway is made to prove the theory results. The examples indicate that the simulation of seepage field under rainfall condition and stress field under moving vehicle loads through ABAQUS software is practicable with satisfactory results.
