COMPOSITE INFINITE ELEMENT FOR MODELING UNBOUNDED SATURATED-SOIL MEDIA

The concept of unbounded soil regions employed in the treatment of problems in geotechnical engineering is discussed. An inifinte element is developed in this paper which provides a convenient numerical alternative for modeling problems with variable soil properties and complex boundary conditions. The accuracy of the element has been verified by comparing numerical solutions with various bench-mark analytical results. By using mesh configurations of different sizes, it was observed that both computational economy and solution accuracy can be improved by the incorporation of infinite elements.
