Introduction In the world of civil engineering and infrastructure development, few structures are as ubiquitous yet as challenging as the box culvert . Found beneath roadways, railways, and embankments, box culverts serve a critical dual purpose: they convey water to prevent flooding and support heavy traffic loads. However, a poorly designed culvert leads to catastrophic failures—road washouts, structural cracks, and even loss of life.
