FINITE ELEMENT ANALYSIS OF THE STRESSES IN SLOPES. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

This paper describes a finite element method to analyse the distribution and changes in stress in a slope when an artificial slope is excavated in a natural slope. The results show that when the artificial slope angle is increased, or when the slope angle changes during excavation, the vertical stress and maximum shear stress in the natural slope will increase rapidly, and will form a stress concentration region at the foot of the slope. A new tensile region will occur and develop at the point where the slope angle has altered. If the slope angle excavated remains unchanged, the influence of the excavation upon the stress distribution will decrease as the natural slope angle increases. These results indicate that the influence of either an increase in design slope angle or of the excavation process upon the three stress distributions within the slope is small at the top of the slope and greatest at its foot. Therefore the possibility of tensile failure has to be carefully analysed at the point the slope angle is altered, and when the slope angle excavated is increased, and at the foot of the slope.
