tailieunhanh - A research for using bazan soil as filling materials of homogeneous earth dams in Tay Nguyen area
The paper investigates the physical characteristics and mechanical behaviors of Bazan soil. Based on that, proposes the approach for quality improvement and design criterion when using Bazan soil for homogeneous earth dams. The result of experiments reveals that Bazan soil has low dry density and high optimum moisture content, which is the cause of difficulty in the construction phase. Whereas, if suppling 10- 12% of mixture weight by using grit, the mechanical properties of mixture is going to be improved significantly and can be used for filling the embankment dam. |
