  1. TOPIC 1:SITEINVESTIGATION 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. (CO1-PO10)

  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. 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
