Simplified design of reinforced concrete box culverts

Апстракт

This International Standard is applicable to the design and construction of reinforced concrete box culverts under the following conditions:
(1) Top slab of the culvert only bears highway vehicle loads, excluding heavy-duty traffic loads such as railway;
(2) The culvert is a inlet unsubmerged culvert, which means the water flow maintains a free surface state throughout the culvert, and there is no water pressure act on the culvert’s top slab;
(3) The single span of the box culvert does not exceed 5 meters.

The standard contains a complete technical regulations for box culvert engineering, including: standard configurations of box culverts, loads, material requirements, structural analysis model, bearing capacities, structural requirements, construction process and quality inspections. Through systematic technical regulations, this standard provides comprehensive technical guidance for box culvert projects meeting the above conditions throughout their entire life cycle.
