Title: Comparison of ultimate bearing capacity prediction for cohesive soil foundation with 3 theoretical formulas
Abstract: Based on the cited data of loading tests and calculation, 3-D finite element analysis is con-ducted with the software ABAQUS. Comparison of 3 theoretical prediction formulas for ultimate bearingcapacity is carried out, which are Vesic's, Hansen's and Meyerhof's. This paper discusses the impact onprediction results of foundation size, foundation embedded depth and soil properties. The results showthat:(1) The prediction errors of these three formulas are relatively low when they are used for shallowfoundation(DB) of cohesive soils. However, none of these three formulas is applicable for deep founda-tion(DB) of cohesive soils.(2) For shallow foundation of cohesive soils, the ultimate bearing capacity istotally overestimated with these three formulas. In general, prediction result of Meyerhof's formula islargest, and Vesic's is closest; when the soils' properties meet the condition of φ25° and c20 k Pa, theprediction errors of these formulas are no more than 10% generally; the prediction errors of these formu-las increase with the increasing of the frictional angle and cohesion of foundation soils.
