COLLINEAR FORCE AND FREQUENCY ANALYSIS OF A VIADUCT PILE FOUNDATION CONSTRUCTION PROJECT: A CASE STUDY ON THE APPLICATION OF BIM TECHNOLOGY

For designers, construction technologists and management personnel, BIM technology allow working more conveniently, swiftly, efficiently, accurately, timely and in a more coordinated manner. These days, China is experiencing rapid economic growth and high population dynamics, resulting in worst traffic congestions, which demands to strengthen the urban transportation infrastructures, of which the railway viaduct is the most common practice. Such viaducts are built in and around most subways. A domestic viaduct project was designed and constructed in Wuhan City. This project faced some new problems and complications in the design and construction phase. An Autodesk Revit Architecture, Ansys, and Structural Bridge Design were used on a BIM platform to study and design this viaduct pile foundation project. The collinear force difference dynamic analysis was conducted using BIM technology as one component of the entire project. Combined station house and viaduct construction deformation and frequency analysis were summarized and evaluated at different weak deformation locations of the viaduct pile project. Early support structures were implemented for tunnel support based on the proposed drill (mine) tunnel deformation monitoring scheme designed during BIM simulations. In the progress of the subway tunnel construction process, unusual circumstances observed during analysis were used as an immediate feedback for construction, supervision, and design of the relevant units, and appropriate support measures were taken to strengthen the tunnelling and piling process. Using BIM technology, the total construction process was optimized, as well as an enhanced system management was realized so that each system components and building steps were clarified during operation. Due to the high linearity of the structure, there were certain difficulties in installing and building the viaduct and the viaduct curves of the station. Based on the feedback from the BIM simulations, n-shaped door frame support structure system and accurate installation of steel box girder were used at the subway station structure of each component to meet the national and international safety standards.
