The general assembly of the project ARSCOP took place on May…

Improvement of the ground investigation and the sizing of geotechnical structures
with the use of pressuremeter
Development of behaviour laws
Consolidating knowledge of realization and interpretation of pressuremeter tests
Development of equipment tests

Context

The pressuremeter is essentially a geotechnical investigation equipment which allows in a single test to evaluate both the deformation and failure properties of soils and soft rocks. It measures the pressuremeter modulus, creep pressure and limit pressure. In the more advanced equipment such as the self-boring pressuremeter, it also measures the initial state of stress in the ground and therefore the coefficient of earth pressure at rest can be obtained.

The work done in France and abroad over the past 40 years has permitted the use of pressuremeter test results as valid design parameters for the design of retaining walls, shallow and deep foundations, soil reinforcement, etc.

However, many interesting points highlighting the challenges for future development of pressuremeter have been put forward for discussion recently and especially:

the subject of limitations of the testing procedure,
the availability of equipment,
the difficulties in the interpretation and analysis of data derived from the test, etc.

To continue with the development of pressuremeter, three aspects of pressuremeter testing must be re-evaluated:

Use of pressuremeter for ground investigation.
Accuracy of displacement calculations for geotechnical structures.
Assessment of the bearing capacities of shallow and deep foundations.

The need for a research program including different work tasks addressing these points and the involvement of the geotechnical profession has been identified.
