• Abstract:
  Concrete box culvert floor slabs are known to have detrimental effects on river and stream hydraulics. ; Consequences include an aquatic environment less friendly to the passage of fish and other organisms. This has ; prompted environmental regulations restricting construction of traditional, four-sided box culvert structures in rivers ; and streams populated by protected species. The box culvert standard currently used by the Kansas Department of ; Transportation (KDOT) is likely to receive increased scrutiny from federal and state environmental regulators in the ; near future. ; Additionally, multiple-cell box culverts present a maintenance challenge, since passing driftwood and debris ; are frequently caught in the barrels and around cell walls. As more structures reach the end of their design lives, new ; solutions must be developed to facilitate a more suitable replacement. Since construction can cause significant delays ; to the traveling public, systems and techniques that accelerate the construction process should also be considered. ; This report documents development of a single-span replacement system for box culverts in the state of ; Kansas. Solutions were found using either a flat slab or the center span of the KDOT three-span, haunched-slab bridge ; standard. In both cases, the concrete superstructure is connected monolithically with a set of abutment walls, which sit ; on piling. The system provides an undisturbed, natural channel bottom, satisfying environmental regulations. Important ; structural, construction, maintenance, and economic criteria considered during the planning stages of bridge design are ; discussed. ; While both superstructural systems were found to perform acceptably, the haunched section was chosen for ; preliminary design. Rationale for selection of this system is explained. Structural modeling, analysis, and design data ; are presented to demonstrate viability of the system for spans ranging from 32 to 72 feet. The new system is expected ; to meet KDOT’s needs for structural, environmental, and hydraulic performance, as well as long-term durability. ; Another option involving accelerated bridge construction (ABC) practices is discussed.
