An Evaluation of the Use of Pore Pressure Coefficients in tne Analysis of Rapid Drawdown in Earth Slopes.
Abstract
The principal changes in stress which are induced in an earth slope as the result of rapid drawdown were estimated using the finite element method. Bishop (1954) proposed using pore pressure coefficients to estimate the changes in pore water pressure induced in an earth slope as the result of rapid drawdown. The assumptions which Bishop made in developing his method were evaluated using the principal changes in stress calculated in this study from the finite element method. In addition, values of the pore pressure coefficient which would be required to give the values of the change in pore water pressure obtained from Bishop's method were calculated using principal changes in stress estimated from the finite element method. Changes in pore pressure were calculated using measured values of the pore pressure coefficient. These values were compared with changes in pore pressure calculated using Bishop's procedure.
