Question

For undisturbed sampling, the penetration of the sampler should be periodic.

(a) False

(b) True

I got this question in a job interview.

This interesting question is from Soil Samples and Samplers in division Stabilisation of Soils, Site Investigation and Sub – Soil Exploration of Geotechnical Engineering II

Answer 1

The correct option is (a) False

To elaborate: For undisturbed sampling, the penetration of the sampler into the soil should be continuous and rapid. The sampler should not be penetrated in a slow and periodic manner.
