Parametric modeling and structure verification of asphalt pavement based on BIM-ABAQUS

摘要

As a result of progressive use of BIM in effective collaboration and sophisticated data management, the amount of diverse project information is rapidly increased, thus its appearance directly led to revolutionary change in intelligent engineering and production mode. However, it has not been quite advanced in supporting road engineering, especially in conducting a structural calculation for asphalt pavement. Relying on the capabilities of BIM and finite element modeling software ABAQUS, this paper proposed a data conversion interface that can not only present three-dimensional visual modeling but also conduct structural calculation for asphalt pavement. A 3D visualization modeling of asphalt pavement was firstly carried out through Revit modeling software. Afterward, the generated model file (.RVT) was imported into the transferring software YJK, and the model was transformed into a file named INP by the transferring software. Thus, the generated model file (.INP) was analyzed by the software ABAQUS. This study effectively strengthened the BIM with structural analysis capability by developing a conversion interface based on BIM-ABAQUS. The framework provided a supporting platform for the integration of BIM-based highway route design and pavement structural analysis in pavement engineering.
