CBR

California bearing ratio

A ratio used in determining the bearing capacity of a foundation; defined as the ratio of the force per unit area required to penetrate a soil mass with a 3 sq in. (19.4 sq cm) circular piston at the rate of 0.05 in. (1.27 mm) per min to the force required for corresponding penetration of a standard crushed-rock base material; usually determined at a penetration of 0.1 in. (2.54 mm).

(1) (Computer-Based Reference) Reference materials accessible by computer rather than print. For example, this encyclopedia.

(2) (Constant Bit Rate) A uniform transmission rate. For example, real-time voice and video traffic requires a CBR. In ATM, CBR guarantees bandwidth for the peak cell rate of the application.

(3) See case-based reasoning.
