The Search for Methods of Factor Analysis for an Optimal Design of Earth-Fill Dams with Stone-Concrete Support Zone

Abstract

An investigation of the stress state of a reinforced concrete face of an earth-fill dam by methods of factor analysis showed that a compilation of quadratic models of the regression equations is needed to achieve an adequate description of the stresses in the face. Through the use of a support zone of stone concrete it is possible to realize a more efficient shape of the dam. The influence of the properties of the support zone on the stress state of the face affects elevations above the lower third of the height of the dam as well as in the section near the crest and is expressed in a negative influence of the excess stiffness of the support zone on the stresses in the face.
