摘要
对AC10型沥青混合料圆柱型试件进行5级单轴静载蠕变试验,提取反映沥青混合料粘弹性的Burgers模型参数。结合此参数展开对沥青混合料的粘弹性分析,将提取的Burgers模型参数导入FLAC3d典型蠕变模型中,进而模拟蠕变试验进程。结果显示,FLAC3d能够较好地模拟蠕变试验。
This paper carries out 5 - grade single - axis creep test with dead load for cylindrical sample of AC10 asphalt mixture and extracts the Burgers model parameter reflecting the adhesive elasticity of the asphalt mixture. Based on this parameter the paper analyzes the adhesive elasticity of the asphalt mixture, introduces the extracted Burgers model parameter into FLAC3d typical creep model and further simulates the progress of creep test. The result shows that FLAC3d can simulate creep test better.
