STABILITY OF LOW EMBANKMENT ON COHESIVE SOIL STRATUM

THE STABILITY OF LOW EMBANKMENTS WITH ARBITRARY SURCHARGE IS EXAMINED BY ASSUMING THAT THE "ANGLE OF SHEAR RESISTANCE = 0 ANALYSIS" IS APPLICABLE AND THE UNDRAINED SHEAR STRENGTH INCREASES LINEARLY WITH DEPTH. IT IS ASSUMED THAT A VERTICAL TENSION CRACK DEVELOPS IN THE FILL ABOVE THE POINT AT WHICH THE SLIP SURFACE EMERGES FROM THE FOUNDATION SOIL. A STABILITY CHART IS COMPILED FROM THE RESULTS OF THE ANALYSIS. THE APPLICATION TO THE STABILITY ANALYSIS OF TWO CASE RECORDS SHOWS THAT THE ACCURACY OF THIS STABILITY CHART IS SATISFACTORY. FOR THE CASE WHERE THE THICKNESS OF A COHESIVE SOIL STRATUM IS LIMITED, THE STABILITY IS ANALYSED BY ASSUMING EITHER CIRCULAR OR PLANE SLIP SURFACES, AND A STABILITY CHART IS COMPILED. THE STABILITY CHART FOR AN EMBANKMENT WITH VERTICAL FACES IS ALSO COMPILED IN ORDER TO MAKE A ROUGH ESTIMATE OF THE STABILITY OF EARTH STRUCTURES SUCH AS SHEETPILE BULKHEADS.
