Question 1: When conducting a consolidation test on a soil sample, what does the oedometer apparatus measure?

Which action should you take?

Choose only one option

The permeability of the soil

The plasticity index of the soil

Settlement of the soil under a controlled pressure

The cohesion of the soil

Question 2: What is the primary purpose of performing a pressuremeter test in foundation design?

Which action should you take?

Choose only one option

To determine the in-situ soil pressure and deformation characteristics under load

To measure the permeability of the soil

To assess the soil's compaction properties

To evaluate the moisture content of the soil

Question 3: In the context of soil compaction, what is the significance of the void ratio?

Which action should you take?

Choose only one option

It measures the total amount of water retained in the soil after compaction

It indicates the degree of particle alignment in the soil structure

It determines the rate at which soil can consolidate under load

It represents the ratio of the volume of voids to the volume of solids, impacting soil strength and compressibility

Question 4: In groundwater management, what **influence does the local climate have on the suitability of dewatering methods on a construction site?

Which action should you take?

Choose only one option

Humidity increases soil compaction during dewatering

Wind speed influences the evaporation rate in dewatering

Temperature does not affect dewatering efficiency

Rainfall patterns impact the efficiency of dewatering systems

Question 5: How does soil consolidation behavior affect long-term settlement for buildings?

Which action should you take?

Choose only one option

Consolidation causes immediate settlement, but it is reversible

Consolidation has no impact on settlement; it only affects the initial compaction

Consolidation increases soil compaction, reducing settlement over time

Soil consolidation involves volume reduction under load, leading to long-term settlement that must be accounted for in design

Question 6: What is the most important factor when selecting the type of foundation for a specific construction project?

Which action should you take?

Choose only one option

The cost of construction for each foundation type

The soil properties, including bearing capacity, type, and settlement characteristics

The distance of the construction site from the nearest material supplier

The aesthetics and architectural design of the building
