摘要
通过有限元对沥青面层温缩裂缝尖端的应力强度因子进行分析,结果表明,在连续降温条件下,影响沥青面层内温缩裂缝应力强度因子的主要因素为初始温度和降温幅度。
Based on the analysis of the FE software, the stress intensity factor of the thermal contracted crack is demonstrated. It is proved that the initially temperature and the changed temperature are main factors which affect the change of the stress intensity factor of the thermal contracted crack in asphalt concrete pavement
