(a) should not exceed  20%

(b) should not exceed  10%

(c) should not exceed  15%

(d) should not exceed  40%

I have been asked this question during an online exam.

I want to ask this question from Soil Samples and Samplers in chapter Stabilisation of Soils, Site Investigation and Sub – Soil Exploration of Geotechnical Engineering II

Answer 1

Right option is (b) should not exceed  10%

Explanation: For soft sensitive soil, the area ratio of sample should preferably not exceed 10%. The thin-wall samplers are those for which the area ratio is less than or equal to 10%. Samplers for which the area ratio is more than 10% are known as thick-wall samplers.
