摘要
Abstract
The problems from failures of concrete gravity dam are briefly reviewed herein,and then the theoretical formula for the reasonable cross-section of gravity dam is derived and analyzed.Furthermore,the reasons why the isosceles triangular cross-section is adopted for the cement-sand-gravel dam and why the cross-secion of gravity dam in japan is a little bit too larger and its upstream is designed with a fold-slope are illustrated,while the differences among the cross-sections designed for the super-high gravity dams with the heights over 200 m at home and abroad are comparatively analyzed.Based on the relevant analysis,it is pointed out that not only the study on the dam stability against sliding is necessary to be deepened in China,but the relevant design criteria for the high dams with the heights over 200 m are also necessary to be deepened.关键词
