Abstract

In order to solve the problem of rock mechanics under complex hydraulic conditions,we have developed technologies regarding in-situ high-pressure true triaxial test and rheological test on rock mass with complex stress path, in-situ large-scale model test as well as fine detection of micro-crack development in failure process of rock mass, and applied them to tackling key technical problems in complex hydraulic rock engineering. Such technical problems include the suitability of building high arch dam in Baihetan columnar-jointed basalt, the mechanical properties of deep buried rock mass under high geostress in Secondary Jinping diversion tunnel, and the long-term deformation prediction of the soft rock foundation of Wujiang Goupitan vertical ship lift. We thereby present some research achievements as follows: (1) The strength parameters of nonlinear strength criterion of columnar-jointed basalt and deep buried marble with the influence of intermediate principal stress into consideration were obtained through researches on the deformation and failure characteristics of rock mass under high geostress and rock mass with complex stress path in cavern-excavating process. (2) The rheological parameters of deep buried marble were obtained via researching the rheology properties of complex structural rock mass under high geostress and with complex stress path. (3) Acoustic emission fine observation of the excavation-relaxation process of columnar-jointed basalt and the failure process of specimens of true triaxial test was accomplished by examining the relaxation properties of columnar-jointed basalt and pre-anchoring anti-relaxation measures. (4) The rheological constitutive parameters of soft rock-pile composite foundation were acquired by studying the rheology properties of soft rock-pile composite foundation of Wujiang Goupitan super high vertical ship lift. Such achievements have promoted the in-situ test technology of rock mass, developed the basic theory of rock mechanics, and offered technical support for solving the new problems of rock mechanics under complex hydraulic conditions.
