Soil Exploration

The purposes of subsoil exploration are listed below, EXCEPT

• Determining the nature of soil at the site and its stratification

• Checking whether the soil surface has an incline relative to the horizontal

• Obtaining disturbed and undisturbed soil sample

• Determining the depth and nature of bedrock

How many phases are there in the Soil Exploration Program?

• two

• three

• four

• five

Below are the lists during Phase 2 of the Soil Exploration Program, which involve the collection of existing subsoil conditions, EXCEPT

• Types of structure to be constructed & its future used

• Existing soil exploration reports prepared for the construction of nearby structures

• Geologic survey maps

• Soil manuals published by the state highway department

Below are the Common Sampling Methods, EXCEPT

• Thin-Wall Tube

• Hand Auger

• Piston Sampler

• Standard Split Spoon

In Standard Split Spoon sampling, the sampler is driven into the soil at the bottom of the borehole by means of

• hydraulic pressure

• manual drilling

• mechanically pushed

• hammer blows

The representative soil samples recovered by split-spoon samplers (disturbed samples) can be used for laboratory tests, EXCEPT

• grain-size distribution

• consolidation

• shrinkage limit

• plastic limit

Which type of sampling is required to obtain a highly undisturbed sample?

• Piston Sampler

• Standard Split Spoon

• Thin-Wall Tube

• Wash Boring
