| Abstract: | Laxiwa project is of thin double-curvature arch dam and its main rock mass is coarse-grained granite in Indosinian epoch at dam foundation and abutments.Thus,a large amount of indoor and in situ rock mechanics tests were carried out,and mathematical statistics analysis and computational analysis of test results were fully and systematically made to achieve deformation behaviour and shear strength of the foundation rock mass as well as rock mass classification.Improvement of rock mechanics methods and selection of mechanics parameters are presented. |

| Keywords: | bedrock rock mass classification rock mechanics deformation modulus shear parameter |
