Many factors about the stability for the reservoir embankments is determined when the facility is completed. Therefore the initialdesign of the embankment is important. Many researchers focused the effect of soil parameters although the cross section greatlyaffects the stability and can be controlled in design step. The objective of this research is to analysis of the effects for the safetyfactor of slope and seepage according to change cross-section in embankment. As a result, the quantity of seepage decreased as thegradient of downstream slope decreased and was proportional to the height of embankments. There was a linear relationship betweenthe gradient of slope and the safety factor of slope. However the gradient of slope did not affect other side slope. All in a relationship,regressive equations with a high correlation coefficient were calculated and can be applied the simple estimation method of the stabilityusing the cross-section. As results of analyzing the sensitivity, the friction angle and permeability critically effect for the slope stabilityand the seepage, respectively. The effect of the slope gradient was similar to major soil properties.
Abstract
Many factors about the stability for the reservoir embankments is determined when the facility is completed. Therefore the initial design of the embankment is important. Many researchers focused the effect of soil parameters although the cross section greatly affects the stability and can be controlled in design step. The objective of this research is to analysis of the effects for the safety factor of slope and seepage according to change cross-section in embankment. As a result, the quantity of seepage decreased as the gradient of downstream slope decreased and was proportional to the height of embankments. There was a linear relationship between the gradient of slope and the safety factor of slope. However the gradient of slope did not affect other side slope. All in a relationship, regressive equations with a high correlation coefficient were calculated and can be applied the simple estimation method of the stability using the cross-section. As results of analyzing the sensitivity, the friction angle and permeability critically effect for the slope stability and the seepage, respectively. The effect of the slope gradient was similar to major soil properties.
