| Abstract: | Combined with the actual construction of Kamchay Gravity Dam in Cambodia， the deep anti-sliding safety coefficients of the dam foundation under the normal storage level of the reservoir are obtained with the elastoplastic strength-reduction finite element method in accordance with the case that if a sudden change of the characteristic point shift occurs and the plastic zones under the whole dam foundation are connected throughout. The calculation result shows that Kamchay Gravity Dam has a higher safety degree of stability against deep slide therein， and then can meet the requirement of the specification concerned. |
