Application of cone penetration test, CPT has been increased in foundation engineering due to supplying continuous and accurate soil profile in recent years. A static analytical model based on general shear failure mechanism of logarithm spiral has been developed for calculating directly bearing capacity of footings, q_ult from cone resistance q_c. The transform of failure mehanism from shallow to deep, foundation dimension and data processing has been considered in the proposed method. Six current CPT direct methods for determining bearing capacity of footings have been investigated. The proposed method and six others were compared to the measured capacity ranging from 1.7 to15 kg/cm² of 21 footings with range of diameter from 0.3 to 3m which compiled in a database. The statistical and cumulative probability approaches for validation of methods indicate optimistic results for proposed method.
