2.2.1 Determine Type of Geotechnical Design and Parameters Required
The type of geotechnical analysis and design depends very much on the type of structures or works
to be designed. Table 2.1 below highlighted the types of works normally carried out by DID and
their associated design components which include various hydraulic structures; embankments and
dams; subsurface drainage; excavations; earth retaining structures and revetment works. The type
of geotechnical analysis required and corresponding to the design components are as in Table 2.2,
namely bearing capacity, settlement, slope stability, seepage, retaining wall, soil and geosynthetic
filter.
