Unsteady Seepage Analysis of Extra-high Core-wall Rockfill Dam During Impoundment by YANG Huigang, LIU Detan, SHANG Yongxi, WANG Junfeng, XU Liqun, HUANG Zhangxin

“…The water level of an extra-high core-wall rockfill dam rises rapidly during the impoundment period.To ensure the seepage stability of key parts such as the core wall,this study determines the calculation conditions according to the actual monitoring data.Based on the unstable saturated-unsaturated seepage theory,the finite element method is applied to calculate the unsteady seepage field of the dam.The calculation results show that the anti-seepage effect of the core wall is good during impoundment.The equipotential lines in the dam body are concentrated on the upstream side surface of the core wall,and the maximum seepage gradient reaches 11.52.The value exceeds the average failure gradient of the core wall in the field test but does not reach the allowable seepage gradient under the protection of the filter layer.Therefore,the seepage stability meets the requirements.The calculation results can provide a reference for the subsequent impoundment of this project and other similar projects.…”
