Analysis of normative and technical documentation for geotechnical monitoring of landslide processes

This study provides an inductive analysis of current normative and technical documentation for geotechnical monitoring. Based on it, the main disagreements and inaccuracies were identified and measures to eliminate them were proposed. During the study, 26 current normative documents were analyzed through 32 criteria. Initially, it was determined whether these documents were included in the List of National Standards and Codes of Practice, which directly affects the obligation to comply with the document requirements. Documents without concrete requirements to monitoring or with limited range of application were excluded from further analysis. The subsequent analysis was carried out according to criteria such as the timing and cyclicity of work; the location of the source and survey points, and their quantity; the accuracy of determining the position of the points; special instructions when working on landslides, etc. As a result, significant differences have been identified among normative and technical documents governing geotechnical monitoring of landslide processes, specifically in their requirements for the timing and cyclicity of work (they range from 1 day to six months). Furthermore, there is no reliable list of controlled parameters that would be identical for several documents. The following research areas have been identified: developing a system of dependencies of the limit values for controlled parameters; standardizing the optimal number of points depending on the scale of landslide phenomena and topographic conditions of work.
