摘 要: 在改扩建工程中,补强段的加铺层设计是重要内容之一。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ANSYS 10�0,假定层间为完全连续,对带裂缝的加铺层结构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,且技术与经济平衡时,增大加铺层厚度有利于结构受力。
关 键 词: 道路工程;加铺层;有限元;力学响应;应力强度因子

Abstract: For reconstruction and extension projects, design of overlay for reinforcement section is one of the important contents. 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.
Key words: road engineering; overlay; finite element; mechanical response; stress intensity factor
