Design and Construction Practice of Earth-Rock Dam for Hua'erwan Reservoir in Langzhong City
Earth-rock dam has become the most commonly used dam type in practical engineering because of its advantages of convenient materials and adaptability to different terrain,geology and climate conditions.After comprehensive technical and economic comparison,the reasonable dam axis and earth-rock dam type of Hua'erwan Reservoir in Langzhong City were determined.According to the terrain and geological conditions,the section and zoning of the dam body were optimized in the preliminary design.In the construction process,the geological defects of dam foundation were dealt with,the filling index of dam shell material was corrected,and the problem that the unit cement consumption of dam foundation grouting exceeds the quota was preliminarily discussed.
