沥青路面荷载型反射裂缝力学计算分析

该文为了探究开裂基层、旧路面结构上沥青加铺层开裂机理,并验证富沥青的沥青砂应力吸收层在防治沥青路面反射裂缝方面的作用效果,首先从建模入手,介绍了有限元模型的建立,继而分析确定了车辆轮载作用在沥青加铺层上的最不利位置,进一步分析了应力吸收层在防治沥青路面反射裂缝中的作用效果。

Analysis of Mechanics Calculation of Asphalt Pavement Loading Reflected Crack

In order to probe into the cracking mechanics of the cracking base and the asphalt paving course on the old pavement structure, and to verify the action effect of the asphalt sand stress absorbing course rich of asphalt in the aspect to prevent the reflected crack of asphalt pavement, the article introduces the establishment of the finite element model firstly from the model establishment, then analyzes and defines the most unfavorable position of the vehicle wheel loading action on the asphalt paving cours...
