IN-SITU & LABORATORY INVESTIGATIONS

What are the two types of Investigations discussed?

• In-situ & Laboratory

• Laboratory & Field

• In-situ & Field

• Field & Ground

a way of confirming the findings of the desk study and having more knowledge of the ground in the field

• Desk Study

• Field Investigation

• Field Reconnaissance

• In-Situ Investigation

What are the 3 types of investigations under field investigations?

• Solid, liquid, and Gas

• Linear, Areal, and Volumetric

• Perimeter, Area, and Volume

• Porosity, Strength, and Shear

The 2 components of in-situ stress that are often measured

• Liquid Stress and Total Stress

• Stress and Solid Pressure

• Tensile Stress and Pressure

• Total Stress and Fluid Pressure

Type of measurement where a static or dynamic load must be applied to the ground.

• Measurement of Deformability

• Measurement of Pressure

• Measurement of Stress

• Measurement of Strength

All are types of measurement under In-Situ Investigation, EXCEPT.

• Measurement of Stress

• Measurement of Shear Strength

• Measurement of Deformability

• Measurement of Hydraulic Properties

• None of the Above

Normally requested when (i) the suitability of a rock or soil for a particular use must be assessed and (ii) their composition evaluated.

• In-Situ Investigations

• Laboratory Investigations

• Field Investigations

• Ground Investigations

What are the three types of tests for composition?

• Physical, Chemical, and Physico-Chemical

• Physical, Mechanical, and Physico-Mechanical

• Chemical, Mechanical, and Physico-Chemical

• Physical, Chemical, and Mechanical

These tests measure the conductivity of soil or rock and the volume of fluid they release by drainage.
