A concrete dam is an important water-retaining hydraulic structure that stops or restricts the flow of water underground streams. It can be regarded as a constantly changing complex system. The deformation reflect its operation behaviors most directly among all effect quantities. However, due to change external environment, failure monitoring instruments, and existence human errors, obtained da...

The grey system theory studies the uncertainty of small sample size problems. This paper using grey system theory in the deformation monitoring field, based on analysis of present grey forecast models, developed the spatial multi-point model. By using residual modification, the spatial multi-point residual model was developed in further study. Then, combined with the sedimentation data of Xiaol...

It is difficult to obtain reliable shear strength parameters for the stability analysis and evaluation of tailings dams in an unstable state. In this study, sensitivity index safety factor a dam was evaluated. The cohesion C range earth rock state determined by factor, Morgenstern–Price method used inversion. During parameter inversion, uncertainty reasoning established based on cloud theory, w...

Deformation mechanism in the core rockfill dams with heavy load and high-stress level is difficult to predict control, which one of key problems be solved dam operation safety management control. Aiming at large error obtained by parameter-based functional models (regression model, grey theory etc.) deformation prediction dams, a fractal method its technical process combining variable dimension...

Coal mine underground reservoir water storage technology is an effective technical way to achieve high efficiency of coal mining and protection resources. The stability pillar dam plays a decisive role in the safe stable operation reservoirs. Mining adjacent working faces long-term erosion are main influencing factors dam. In this paper, fluid-solid coupling calculation model for deformation ev...
