1. TOPIC 1: SITE INVESTIGATION FOR FOUNDATION DESIGN
WEEK2
INTERPRETATION OF SI BORELOG
LABORATORY STRENGTH PARAMETERS

2. Learning Outcomes Student should be able to:
Explain how SPT are done (CO1-PO10)
Derive information from the borelog.
(CO1-PO10)
Discuss sampling method and the laboratory
tests to determine the soil properties.

3. Class Exercise
Students shall form groups of 3 to 5 students. Each group will be given actual Soil Investigation Report. Students to study the report and derive information from it. Tasks:
1) Pick two boreholes and draw a soil profile between the two boreholes

4. 2) Determine the following items:
Type of formation
Range of water table depth
Range of bedrock/hard layer depth
Type of sampling
What are the laboratory tests

5. Grain Size Distribution Atterberg limits
Laboratory Tests
Grain Size Distribution
Atterberg limits
Chemical tests- Ph, organic matter, sulphate, chloride
Triaxial tests
Unconfined compression test on undisturbed sample – can be used to determine parameter c

6. Compression test on rock core – for strength determination.
Consolidation test
