INFLUENCE OF SOIL ENGINEERING CALCULATION METHODS ON THE PROOF OF STABILITY OF SYSTEMS BUILT ON SLOPES

THE CONCEPT OF STABILITY IS DEFINED AS THE QUOTIENT OF THE FORCES WHICH OPPOSE THE SHEAR FORCES. TOTAL NORMAL FORCE AND TOTAL SHEAR FORCE OF THE RUPTURE SHEAR ZONE HAVE TO BE DETERMINED. A DESCRIPTION OF FIVE METHODS OF CALCULATION FOLLOWS: (1) NORMAL AND SHEAR FORCES OF THE PARTIAL RUPTURE SHEAR ZONES ARE ADDED ARITHMETICALLY; FORCE, DIRECTIONS AND FORCES BETWEEN THE PARTIAL RUPTURE SHEAR ZONES CANNOT BE OBTAINED. (2) THE SAME METHOD AS 1, BUT WITH A GEOMETRIC ADDITION; THE SUBSEQUENTLY ASCERTAINED NORMAL FORCE IS TOO SMALL AND THE SHEAR STRENGTH IS TOO GREAT. (3) ARBITRARY ASSUMPTIONS ARE MADE TO CONSIDER THE SHEAR FORCES BETWEEN THE PARTIAL RUPTURE SHEAR ZONES. (4) ACCORDING TO THE GRAPHIC METHOD OF MARTIN, THE SHEAR FORCES CONVEYED BETWEEN THE PARTIAL RUPTURE SHEAR ZONES HAVE THE SAME DIRECTION AS THE EARTH PRESSURE; THIS IS THE MOST ACCURATE METHOD. (5) THE SHEAR STRENGTHS BETWEEN TWO PARTIAL RUPTURE SHEAR ZONES HAVE THE SAME DIRECTION AS THE PLANE OF RUPTURE OF THE SLOPING RUPTURE SHEAR ZONE; THIS IS A SIMPLIFICATION OF METHOD 4. /FG/RRL/
