...An optimization of the contour blasting method during the excavation of the rock slope at the Three Gorges Project LU WENBO Wuhan University, Wuhan 430072, PR.China ABSTRACT: On the basis of the theoretical analysis of the blast induced damage in the remaining rock mass. questions such as tl~c O...

.... If the rock mass is excavated, the residual stress would be further released. For example. the rock mass of the Three Gorges Project permanent ship-lock slopes had ever undergone six great structural actions: Before Jinning (Dynasty) action, Jinning (Dynasty) action, Chengjiang action, Yinzhi action. Yanshan...

... ABSTRACT: The middle-isolation piers is one of the key structures of permanent shiplock of Three Gorges Project on Yangtze River. China. This paper deals with the study on forecast deformation of middle-isolation piers of the second shiplock chamber. The time series analysis and grey system...
