Geotechnical Investigation and Testing - Field Testing - Part 6: Self-Boring Pressuremeter Test
Also Known As:
The DIN EN ISO 22476-6 standard specifies the requirements for conducting pressuremeter tests with the self-boring pressuremeter (SBP) as part of geotechnical investigation services. These tests are conducted to measure the deformation of soils and weak rocks in situ by applying pressure to a cylindrical flexible membrane and observing its expansion and contraction.
The SBP is designed to be used in drilling into the ground, and it features an integral self-boring head at its lower end. This design allows the probe to replace the material it removes, creating its own test hole and minimizing disturbance to the surrounding soil. The standard emphasizes the need to measure and record the pressure applied to the probe and the corresponding expansion, in order to obtain the stress-displacement relationship for the soil being tested. The data is recorded automatically during both the boring and testing processes.
