INTEGRATION OF GEOTECHNICAL CONTROL METHODS IN AUTOMATED MONITORING OF THE STABILITY OF NATURAL AND TECHNICAL OBJECTS
Abstract
The paper considers the methodology and algorithms for integrating geotechnical control methods in assessing the stability of natural and technical objects. In the process of creating data processing algorithms for control systems of natural and technical objects, it is necessary to be based on the purpose and system methodology of the control itself. The purpose of the control is to assess the current state of the object based on the measured geotechnical data and to forecast the development of possible destructive processes. In practice, due to the complex structure and various factors that affect the accuracy of the forecast, it is quite difficult to solve the tasks set, and sometimes it is not possible at all. The complexity of the solution directly depends on the applied process models and models of noise-generating factors. One of the most effective approaches is the complex joint processing of deformation and geodynamic control data. Joint processing of heterogeneous data of geotechnical and geodynamic monitoring involves step-by-step processing at three levels of the telemetric system of geotechnical monitoring: physical, channel and network. The physical layer is hardware and represents a set of physical methods for obtaining information (inclinometry, geoelectrics, strain gauge). At the channel level, pre-processing of heterogeneous data and storage of primary and processed data, auxiliary information is carried out: measurement and processing methods, local-level models, required and fixed positions in the space of primary converters. In addition, this level assumes the presence of predictive modules. The network layer is represented by software modules for distributed processing and correction of local-level data, identification and prediction of the initial phases of hidden deformation processes, as well as correlations in the "geological environment - engineering object" system. For the coordinated operation of the local level measurement systems, the network layer generates synchronization and control signals. The considered approach of joint processing of heterogeneous data of geotechnical and geodynamic control was tested by monitoring the dynamics of the karst zone area near the village Chud of the Nizhny Novgorod region (Russia).
