Influence on Stress and Strain of High Embankment Dams Caused by Different Reservoir Filling Path

Abstract

For computing the stress and strain of embankment dams, FEM is employed. Two reservoir filling paths which are constructing filling and completed filling are considered to affect the computing results. It is proved that constructing filling path can enhance the stress of embankment dams. So constructing filling path can take from the hydraulic fracturing of core wall. In addition, constructing filling path can decrease the amount of settlement, and can control the displacement of dam shoulders. In a word, constructing filling path is prior to completed filling path.
