Relaxation Analysis of the Arch Dam Foundation Rock Masses of Jinping I Hydropower Project
The arch dam of Jinping I hydropower station is on obvious high ground area, and the foundation rock masses may relaxed while excavating. Limit tensile strain is put forward to be relaxation criterion. By three-dimensional elastic-plastic finite element method analyzing, and imitating the dam excavating steps, the maximum principle strain of the dam foundation rocks is obtained. The research indicates that the maximum principal strain of upstream side is greater than that of downstream side commonly, and some area would relaxed, with 41m maximal relaxed depth. By engineer analogical research with Xiaowan arch dam foundation rock mass, which have relaxed while excavating, the calculate method and criterion of this paper are reliable, and they can provide reference for engineer design.
