108 GeoMan drawing sheets, each one idea from geotechnical engineering drawn on a single sheet with a drawing title block. 108 have their own page with the full image.

An order to read the sheets in if you are new to geotechnical engineering: basics first, then practice.

  1. 01GEOMAN-049 THE GEOSCIENCESWhere geotechnical engineering sits among the earth sciences. The most saved sheet in the series.
  2. 02GEOMAN-053 PARTICLE SIZE DISTRIBUTIONParticle size is the first thing a soil description tells you.
  3. 03GEOMAN-030 EFFECTIVE STRESSEffective stress is the idea every later sheet relies on.
  4. 04GEOMAN-088 THE AGESHow deep time shapes the ground: the age of a deposit tells you what to expect from it.
  5. 05GEOMAN-029 MOHR'S CIRCLE OF FAILUREMohr's circle links stresses to failure and to the strength parameters on a lab report.
  6. 06GEOMAN-055 DRAINED AND UNDRAINEDDrained and undrained behaviour decides which strength to design with.
  7. 07GEOMAN-034 UNSATURATED SOILSMost ground near the surface is not saturated, and suction changes how it behaves.
  8. 08GEOMAN-016 FOUNDATION TYPESThe family of foundation types: shallow, deep, piled raft and rigid inclusions.
  9. 09GEOMAN-039 EMBEDDED RETAINING WALLSThe main kinds of embedded retaining wall in plan, from sheet piles to diaphragm walls.
  10. 10GEOMAN-050 LANDSLIDESA rotational landslide and the part water plays, the kind of failure the casebook keeps returning to.

Topic groups

The groups read in order, from the ground itself to design and practice. A sheet can sit in more than one topic.

1 Ground and geology

How the ground formed, how geology is described, and the rock and geological models every design starts from.

2 Site investigation and testing

Finding out what is in the ground: drilling, in situ tests such as the CPT and SPT, laboratory tests, and monitoring during construction.

3 Soil behaviour

Effective stress, strength, stiffness and drainage, plus the soils that cause trouble: reactive clays, acid sulfate soils and contaminated ground.

4 Slopes and landslides

Landslides, sinkholes and slope stability: how slopes fail, and how we analyse and manage them.

5 Earthworks and pavements

The earthworks, pavements and rail formations built on and from soil: compaction, settlement and performance.

6 Soft ground and ground improvement

Making weak ground fit for use: compaction, stabilisation, soil mixing, geotextiles and sprayed concrete.

7 Retaining and excavations

Retaining walls, anchors and basements: wall types, earth pressures and the stages of an excavation.

8 Analysis and practice

Numerical analysis and software, and the profession itself: its ideas, its history and how engineers work.

9 Foundations, piling and marine

Shallow footings, piles and piled rafts, and foundations in marine and offshore ground.
