摘要
以京津塘高速公路改扩建工程为依托,结合旧路破损状况,采用大型有限元分析软件ANSYS10.0,假定层间为完全连续,对带裂缝的加铺层结构的各路面参数进行敏感性分析。结果表明:当采用旧路带裂缝的加铺模型时,在技术与经济平衡的条件下,增大加铺层厚度有利于结构受力。
Based on the reconstruction and extension project of Beijing-Tianjin-Tangshan expressway,considering the damage condition of old road,using the large-scale finite element analysis software ANSYS 10.0 and assuming the contact condition as continuity,pavement parameter sensitivity analysis was done for overlay structure with crack on. The results showed that when the overlay model with the old road cracked was used,in the condition of balance between technology and economy,increasing the thickness of overlay was good for the structure stress.
