混凝土路面板裂缝对路面耐久性影响及裂缝防治

早期塑性收缩裂缝的存在,轻则影响路面的外观质量,重则对路面整体性和行驶连续性有不同程度的影响。通过应用有限元软件ABAQUS对裂缝开裂和扩展规律采用断裂力学理论进行力学分析,得出塑性裂缝与路面使用寿命之间的规律。并介绍了塑性裂缝的防治措施。

The existence of Early plastic shrinkage cracks Light affects the appearance of surthce quality, seriously have varying degrees of impact to wholeness pavements and continuity. In order to study the Effects of plastic shrinkage cracks on pavement durability, the paper uses fracture mechanics and FEM software ABAQUS to analyse the law of cracking and crack extension, then draw the law between plastic crack and pavement life. And introduced the plastic crack prevention measures.
