Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1206
... and external water pressure is analyzed by the three-dimensional finite element method. The optimization of concrete lining is carried out to reduce the lining thickness. Under the condition that the quality of backfill grouting is ensured to form a combined bearing body, the combined bearing is smaller than...
