摘要：

为了揭示沥青混凝土的开裂特性，基于有限元软件ABAQUS，采用双线形黏聚区模型对沥青混凝土半圆弯曲试验进行模拟，将模拟得到的荷载-线位移曲线与试验结果进行对比以验证黏聚区模型在开裂分析中的适用性，进一步分析半圆弯曲试件在开裂过程中的内部应力分布、系统能量平衡和断裂性能参数，以及黏聚区模型参数对试件荷载-线位移的影响。结果表明：双线形黏聚区模型在沥青混凝土开裂分析中具有良好适用性；在加载过程中半圆弯曲试件经历了弹性、损伤和断裂阶段，裂纹失稳扩展点并非对应峰值载荷，采用峰值载荷计算断裂韧度结果将会偏大，少部分断裂功会转换为试件未开裂区域的弹性应变能，采用断裂功计算断裂能结果也将会偏大；半圆弯曲试件开裂过程中所能承受的峰值载荷主要取决于沥青混凝土抗拉强度而非断裂能。

Abstract:

To explore the cracking characteristics of asphalt concrete， a finite element software ABAQUS was employed to simulate the semi-circular bend （SCB） test of asphalt concrete using a bilinear cohesive zone model （CZM）. The simulated load-load line displacement curve was compared with the experimental result to validate the applicability of the CZM in cracking analysis. Based on this， the internal stress distribution， system energy balance， fracture behavior parameters during the cracking process of the SCB specimen， and the effects of cohesive zone model parameters on the load-load line displacement of the specimen were analyzed. The results indicate that the bilinear CZM has good applicability in cracking analysis of asphalt concrete. During the loading process， the SCB specimen undergoes elastic， damage， and fracture stages. The point of instability of crack propagation does not correspond to the peak load， leading to an overestimation of fracture toughness when calculated using the peak load； a portion of the fracture work converts into elastic strain energy in the uncracked region of the specimen， resulting in an overestimation of fracture energy when calculated using fracture work. The peak load that the SCB specimen can withstand during the cracking process mainly depends on the tensile strength of asphalt concrete rather than fracture energy.
