Abstract:By employing wave velocity test and deformation monitoring method,the use of checking different standards according to different zones,sections,layers and classification of rock masses,a re-evaluation of rock mass quality is carried out during construction period. Based on the nonlinear finite element method,the overall stability of the typical stage of the construction period of dam is simulated. The real mechanical parameters of rock mass are obtained by feedback analysis based on the geophysical results and monitoring data of field deformation and stress. The numerical results reflect the working condition of the dam in construction and operation periods,and also guide the construction process. The conclusions from this study have been applied to the design of Xiluodu project and are also beneficial to the design and construction of the similar projects.
