THE APPLIED RESEARCH OF THE BEARING CAPACITY OF FOUNDATION OF THE THREE STRENGTH CRITERION
To research the difference of three strength criterion,the unified equation of the Mohr-Coulomb、SMP、LadeDuncan was derived based on the plane strength theory.The difference of plastic interface and the laws of internal friction angle,stick and over consolidation ratio to the plastic load and the critical load were also researched.By compared the results,the plastic load when considering k0 was very small,but the critical load was very big.The results of plastic and critical load by using the M-C failure criterion were similar with the results by using SMP failure criterion which considered the impact of the K0 and intermediate principal stress only if the internal friction angle was small.Similarly,The results of the plastic load by considering the over consolidation ratio or not were almost consistent,but the OCR had a greater influence of the critical load.The method by deriving from this paper is practical for plane strain condition such as retaining wall,slope and other similar engineering.
