Abstract

In bridge engineering, pushing technology has significant advantages in crossing highways, railways, flood control embankments, and bustling urban streets. However, in actual construction, various technical difficulties may also be encountered due to structural and on-site environmental factors. This paper combined engineering practice to explore the technical difficulties in pushing construction of steel box girders for multi-unit super long urban viaducts, including instability problems during the pushing of the main girders, reasonable launching nose length, and reasonable connections between links. Finally, a systematic analysis method was developed to solve technical difficulties in engineering construction and ensure the smooth implementation of the projects.
