The invention discloses a side
slope stability intelligent monitoring and supporting optimization method based on digital twinning, which comprises the following steps: extracting gradient, curvature and geological layering characteristics from a holographic
terrain model, calculating a preliminary change trend of
stress distribution of a rock-soil body in combination with a finite
element analysis method, and determining spatial position distribution of a potential sliding surface of a side slope; according to the space coordinate set of the real-time monitoring point position, the
data acquisition frequency of the sensor is adjusted through a
time sequence analysis method, and a high-frequency
monitoring data set reflecting dynamic changes of stress and underground water is obtained; extracting stress peak values and underground
water level fluctuation characteristics from the high-frequency
monitoring data set, and generating a multi-dimensional information matrix containing
terrain, stress and
water dynamics by combining spatial characteristics of the holographic
terrain model and adopting a data fusion
algorithm; according to the state parameters of the digital twinborn body, if it is judged that the
stress distribution exceeds a preset threshold value, the
stress distribution of the supporting structure is recalculated through finite
element analysis, and an adjusted slope supporting design scheme is obtained.
