摘要

The basic principles of concrete barriers are not generally known or understood. Concrete barriers appear to be simple and uncomplicated, but in reality, they are sophisticated safety devices. When most people think of concrete barriers, they think of the New Jersey Concrete Safety Shape Barrier (NJ-shape or Jersey barriers). For the more common shallow-angle hits, the NJ-shape is intended to minimize sheet metal damage by allowing the vehicle tires to ride up on the lower sloped face. (See figure 1.)
