摘要
半刚性基层沥青路面为当前沥青路面的主要结构形式之一。以京津塘高速公路改扩建工程为依托,以壳牌设计软件BISAR 3.0为计算工具,考虑层间光滑及层间连续两种层间接触条件,并用MATLAB 7.0软件将各主要力学响应量进行三维化处理,对半刚性基层沥青路面在不同层间接触条件下的力学响应分布进行了全面的比较和分析。结果表明:当层间接触条件由完全光滑变为完全连续时,半刚性基层沥青路面的力学响应分布发生明显变化;与层间光滑条件下而言,层间连续条件下半刚性路面具有较明显的力学优势。
Semi - rigid pavement is one of major structural forms of asphalt pavement at present. Based on the reconstruction project of Beijing - Tianjin - Tanggu Expressway, this paper examines the mechanical response distribution of asphalt pavement with semi - rigid course under the different contact conditions, using the Shell design software, BISAR 3.0, as a computing tool, and three- dimensional treatment being carried out with MATLAB7.0 software, in consideration with contact conditions between two courses, i.e. , smooth and continuous contact conditions. It has been shown that the change of above response distribution is obvious when the contact condition changes into the continuous condition from the fully smooth one. Compared to the smooth condition, the semi -rigid pavement has an advantage under the continuous interface contact condition.
