采用ABAQUS有限元软件建立三维沥青路面模型,模拟柔性基层沥青路面在不同的结构层模量组合下的力学响应,研究结构层模量对柔性基层沥青路面的力学响应(应力、应变和位移)。结果表明:沥青路面结构层模量对柔性基层沥青路面力学响应有重要影响;对于柔性沥青路面,要确保下面层有足够的模量,并且选择合宜的柔性基层模量;在路面设计、施工中需要注重中、下面层与柔性基层的施工质量。
The three-dimensional asphalt pavement model was established by ABAQUS finite element software to simulate the mechanical response of flexible asphalt pavement under different structural layer modulus combinations. The mechanical response (stress, strain and displacement) of structural layer modulus to flexible asphalt pavement was studied. The results show that the modulus of asphalt pavement layer plays an important role in the mechanical response of flexible asphalt pavement. For flexible asphalt pavement, it is necessary to ensure that there is enough modulus in the lower pavement, and the appropriate flexible base layer modulus is selected. In pavement design and construction Need to pay attention to the construction of the grassroots, the following layers and the quality of construction.
