Hard And Soft White Layered Rock Mass Deformation Parameters Of Theoretical Research And Engineering Applications

In the actual project, frequently meets project rock mass composed by soft and hard alternated layered rock mass with different lithological character. This kind of rock mass is the compound rock mass by which the different deformation parameters the rock mass is composed. The compound rock mass deformation parameters is not decided by some stratified rock body deformation parameters, but decided by the deformation parameters, the rock layer inclination angle and thickness of each rock layer. It has the extremely vital significance for the project with this kind of rock mass as the ground how correctly comments the deformation parameters of soft and hard alternated layered rocks.This paper soft and hard alternated layered rock mass take the dam bedrock mass of Yangtze River Guan Yin Yan hydroelectric power station as a prototype, through is reasonable generally melts, theoretically infers the relations between stress and strain of the soft and hard alternated layered rock mass under exogenic process and obtains the synthesis modulus of deformation theory solution of soft and hard alternated layered rock mass. Develops the single stratified rock mass home position distortion experiment of all sorts of rock mass in the Yangtze River Guan Yin Yan hydroelectric power station project scene (conglomerate, sandstone, siltstone and mudstone) and the home position large-scale experiment of compound rock mass, further confirms the synthesis modulus of deformation theory solution of layered rocks body. Carries out physical model synthesis distortion experiment of corresponding two kind of rock mass and three kind of rock mass with certain thickness compared to the under specific inclination angle under, carries on the confirmation to the layered rocks body synthesis modulus of deformation theoretical formula. Finally uses on international general most advanced non-linear finite element analysis software to carry on the value analog computation to the layered rocks body synthesis modulus of deformation, and carries on the theory solution, the scene home position experiment, the physical analogue experiment and the numerical analysis synthesis appraisal.Through contrast analysis the theory, experimental and the value simulation of soft and hard alternated layered rocks mass synthesis deformation parameters, establishes the perfect step of layered rocks mass synthesis modulus of deformation to solve from the theory to the experiment again to the numerical analysis. Obtains can apply to the actual project layered rocks mass synthesis modulus of deformation solution method...
