ACTIVE PRESSURE FOR CIRCULAR CUT WITH BEREZANTZEV'S AND PRATER'S THEORIES, NUMERICAL MODELING AND FIELD MEASUREMENTS

Abstract

A simplified slip line solution of the axi-symmetric active earth pressure based on a general lateral stress coefficient for general c-ψ soil system is developed in the present paper. The results from the simplified slip line analysis are compared with those by Prater and results from numerical modeling. It is found that Prater's method may give surprising results and the limitations of Prater's results are also discussed in this paper. The authors have also investigated the importance of the lateral stress coefficient and the lower bound of the coefficient which are not considered in the past.
