Description

technical field [0001] The application relates to a rock time-dependent deformation prediction method and system based on LSTM deep learning, which belongs to the field of rock time-dependent deformation prediction methods in geotechnical engineering and geological disaster prevention and control. Background technique [0002] The essence of rheological characteristics of rock is the time effect of its stress and strain. In general, rheological studies mainly include creep, stress relaxation, long-term strength, elastic aftereffects and hysteresis effects (viscosity effects). Rock creep refers to the process in which the stress remains constant and the deformation increases with time, so it is most closely related to engineering and has received special attention from scholars. [0003] The rheological characteristics of rock are closely related to the long-term stability and safety of rock engineering, such as slope engineering, tunnel engineering, nuclear waste storage, h...
