When conducting geotechnical monitoring, it is necessary to timely detect early negative changes in areas of the geotechnical system to prevent emergency situations and assess the accuracy of forecasts. This article has developed an adaptive algorithm for spatio-temporal information processing of geotechnical monitoring data, which allows us to assess the trend in the stability of the geotechnical system during the bifurcation period. For early detection of negative changes and identification of mechanisms for assessing the transformation of the geotechnical system during the bifurcation period, the parameters of the data collection and processing are changed in the algorithm. These parameters change depending on the selected key zones of the components of the geotechnical system , in which hidden geodynamic processes occur and when the values of the controlled parameters of the technical condition of construction objects are exceeded. The article presents the layout of key objects of the geotechnical system distributed over the observed area. A block diagram of the adaptive processing of heterogeneous geotechnical monitoring data is presented that implements the processing and combining of heterogeneous data to predict the initial phase of development of dangerous destructive processes. The algorithm was used for geotechnical monitoring in the village of Chud in the Nizhny Novgorod region in the period from May 2018 to February 2019. The algorithm allowed to increase the efficiency of early detection of hidden destructive processes and their harbingers.
