Abstract
The aim of this study is to develop a mobile overpass design with a movable damping foundation that ensures safe and continuous traffic flow during the repair of underground utilities. The scope of the research includes the analysis of loads on the overpass foundation and the development of an engineering solution to prevent trench collapses. The study examines vertical and horizontal loads acting on the support foundation and proposes an original movable foundation structure using thixotropic and viscoplastic materials. The research methodology is based on the application of rheological models to describe the behavior of materials that absorb the kinetic energy of vehicles. The obtained results demonstrate the effectiveness of the proposed solution in reducing the risk of trench slope instability, enhancing safety, and improving deternmental conditions. The developed structure can be applied in urban construction and in the organization of temporary road infrastructure
