In Situ Testing in Geomechanics The Main Tests [Paperback]

Demanding a thorough knowledge of material behaviour and numerical modelling, site characterisation and in situ test interpretation are no longer just basic empirical recommendations.

Giving a critical appraisal of the understanding and assessment of the stress-strain-time and strength characteristics of geomaterials, this book explores new interpretation methods for measuring properties of a variety of soil formations.

Emphasis is given to the five most commonly encountered in situtest techniques:

• standard penetration tests
• cone penetration tests
• vane test
• pressuremeter tests
• dilatometer tests

Ideal for practising engineers in the fields of geomechanics and environmental engineering, this book solves numerous common problems in site characterisation. It is also a valuable companion for students coming to the end of their engineering courses and looking to work in this sector.
