Ground water lowering in loessial collapsible soils

摘要

In the last decades, a general underground water level rise have been occurred in loessial collapsible soils, particularly in Braila and Galatzi cities .The paper evaluates the loess structure collapse phenomenon , drainage capability of loess and an energy correlation between gravitational and vegetal drainage . The paper also evaluates engineering solutions in order to drain underground water and to depress its level.
