27、cal works.NOTE ISO 18674 fulfils the requirements for general rules for the performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills, and of geotechnical works as part of the geotechnical investigation and testing according to EN 1997-18and EN 1997-29.Sp

28、ecifically, this part of ISO 18674 applies to field instrumentation and measurements carried out in connection with site investigations of soils and rocks, in connection with Observational Design procedures, in connection with the performance of geotechnical structures before, during, and after cons

29、truction, for ground behaviour evaluation, e.g. unstable slopes, consolidation etc., for the proof or follow-up of a new equilibrium within the ground, after disturbance of its natural state by construction measures (e.g. foundation loads, excavation of soil, tunnelling), for the proof or follow-up

30、of the stability, serviceability, and safety of structures and operations which might be influenced by geotechnical construction, for perpetuation of evidence, and for the evaluation and control of geotechnical works.2 Normative referencesThe following documents, in whole or in part, are normatively
