Finite Element Analysis Technology Application in Studies on CRCP Pavements Subject to Forces

摘要: 文章通过工程实例借助ABAQUS有限元软件，建立CRCP板的路面模型，通过调整路面结构系数，包括CRCP层厚度、C35调平层厚度、地基反应模量大小，进行路面结构响应的参数敏感性分析。分析不同结构设计方案对CRCP板受力的影响，进一步探讨分析、验证和优化设计方案，对于今后连续配筋混凝土路面关键技术的高速发展具有重要意义。

Abstract: By engineering examples and the finite element software (ABAQUS), the CRCP-plated road model was established in this article. The response sensitivities to pavement structure parameters were analyzed by adjusting these parameters such as the thickness of CRCP, C35 leveling layer and the ground modulus. The stress effect of the CRCP plates in the different structural designs was inves-tigated to further analyze, verify and optimize the design. It plays an important role in the rapid development of key technologies in continuously reinforced concrete pavement.
