INTERPRETATIVE REPORT
Each student shall prepare an interpretative report on a site investigation for the reservoir and
associated structures, as shown on drawing ‘Site Plan’. The aims of this report are to outline the
structural properties of the site in relation to the proposed development, carry out initial design
calculations for the proposed work, advise on any problems that may occur on the site during and
(or) after construction and suggest justifiable ways of overcoming any problems identified.
Using the parameters given each student must individually complete the following sections:
1. Laboratory report: using the parameters obtained in the laboratory each student must
individually prepare a report (see Laboratory Reports sheet), which should include a copy of the
relevant British Standard for testing, and a full set of test results, which shall include all
calculations. It would be appropriate to undertake the calculations using a spreadsheet. A part of
this report shall include detailed comments on the use of the tests undertaken and the conformity
of the material tested to appropriate specifications used in geotechnical engineering.
2. Interpretative report - the presentation of the report must be to a very high and accurate
standard i.e. you are employed by the client to produce a series of professional design
calculations – marks will be deducted if this is not achieved.
3. Strata Conditions – comment on how the strata profiles/conditions would have been obtained
(types of site investigation) and summarise the strata conditions for the proposed development –
produce a plan and cross sections of strata conditions - include the angle of dip and strike lines.
4. Earth Filled Dam – design & stability; flow through and beneath the dam; design check for
piping.
5. Slope stability – the stability of the reservoir’s slopes; the stability of the dam (up/down
stream) – reservoir empty/full/rapid draw down (effective and total stress parameters – bulk, dry
and saturated unit weights)
6. Spillways – foundation design and settlement analysis – find a suitable pad foundation for the
spillway; consider the settlement.
7. Pump House – design, bearing capacity and settlement; the structure of the pump house is
considered to impose a 40 kN/m 2 on a raft foundation 32m by 18m.
8. Retaining Wall – a retaining wall is required to the northern boundary of the pump house site –
there are several types of retaining walls – consider which type of wall will be the most
suitable – design the wall.
