(i) Explain with the aid of a sketch and equations why some deep
cuttings in stiff clay collapse during excavation whilst others in
stiff clay survive and collapse after tens or hundreds of
years.
(ii) Explain with the aid of a sketch and equations why it may
be possible to build a higher embankment over soft clay deposits
when the embankment is raised (built up) slowly.
