| 摘 要： | 基于Winkler地基模型,应用ABAQUS有限元软件,按照"贡献面积"刚度分配原则,通过在相邻混凝土板侧面的对应结点设置弹簧单元,建立了考虑接缝传荷能力的机场刚性道面三维有限元分析模型.应用该模型,针对不同地基强度上的典型道面结构,分析了重型落锤式弯沉仪(HWD)承载板、单轴双轮和双轴双轮三种荷载形式作用在接缝一侧板...

| Abstract: | Based on Winkler foundation,a comprehensive 3D finite element model to analyze the structrual response of jointed rigid airport pavement was established by ABAQUS software.Bending stress and deflection for typical pavement structure on edge loading case were calculated under various landing assemblies with varying subgrade strength and joint stiffness.A new relationship model between the deflection load transfer efficiency obtained from bearing plate of Heavy Weight Deflectometer(HWD) and joint stiffness wa... |
