Description (English):

This document specifies the equipment requirements, execution of and reporting on self-boring pressuremeter (SBP) tests. NOTE This document fulfils the requirements for self-boring pressuremeter test as part of the geotechnical investigation services according to EN 1997-1 and EN 1997-2. Tests with the self-boring pressuremeter cover the measurement in situ of the deformation of soils and weak rocks by the expansion and contraction of a cylindrical flexible membrane under pressure.

Abstract

Overview

ISO 22476-6:2018 - Geotechnical investigation and testing - Field testing - Part 6: Self-boring pressuremeter test (SBP) specifies the equipment requirements, execution and reporting for self-boring pressuremeter tests. The standard covers in situ measurement of soil and weak rock deformation by expanding and contracting a cylindrical flexible membrane, and it fulfils requirements for geotechnical investigation services referenced in EN 1997-1 and EN 1997-2.

Key technical topics and requirements

Equipment and probe design
- Composition and function of the self-boring pressuremeter probe, including the central measuring cell, membrane, core, fluid lines and protective “Chinese lantern”.
- Minimum volumetric expansion capability (≥ 25% of initial volume) and a minimum slenderness ratio (expanding length/diameter ≥ 4.0).
- Use of at least three displacement transducers to monitor mean radial expansion and non‑circular deformation.
- Pressure transducer locations (above ground or inside probe,
