Resumen:
This document deals with the technical principles for measuring equipment requirements, the execution of and reporting on the parameters of measuring while drilling method (MWD) as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2. The measured, calculated and derived drilling parameters (e. g. depth, advancement rate, pull down pressure, torque, rotation rate, mud pressure, mud flow, vibration, penetration resistance, soil-rock resistance) can produce useful data about the lithology of the layers for a reliable geotechnical model, their density or weathering, the localisation of voids or faults in the ground, the depth to rock and other properties like permeability. This document describes the procedure for the logging (measuring versus depth) of drilling parameters and how to report them for subsurface characterization. It applies in natural soils, treated or untreated fills and in soft and hard rocks, either on land or off-shore.
