| 摘要： | Continuously reinforced concrete pavement (CRCP) contains continuous longitudinal reinforcement with no trans-verse expansion within the early life of the pavement and can continue to develop cracks in the long-term. The accurate modeling of CRCPs main features is of primary importance in a mechanistic-empirical pavement design procedure. Design tool such as CRCP-9 and CRCP-10 have the capability to analyze continuous pavements under traffic, environmental, and thermal loads and has the capability to predict crack spacing. CRCP-9 and 10 were developed using 2-D and 3-D finite element theory to calculate stresses in concrete and steel bars due to environmental loads. In order to develop a reliable model that better represents the behavior of CRCP, a clear understanding of the interaction between the concrete and steel is essential. Therefore, a parametric analysis was developed, using the 3-D finite element model of the CRCP computer programs in ABAQUS, to investigate the concrete stress distribution while varying the slab thickness. |
