Question 1: During a site analysis, how does the presence of a high groundwater table affect foundation design?

Which action should you take?

Choose only one option

It improves soil cohesion and reduces settlement

It decreases the risk of settlement

It has no effect on foundation stability

It increases the risk of hydrostatic uplift and foundation buoyancy

Question 2: How is the soil's compaction measured using the Proctor Test?

Which action should you take?

Choose only one option

By assessing the volume changes in the soil during consolidation

By measuring the soil's ability to resist shear stress

By measuring the fluid permeability of the soil

By determining the optimum moisture content and dry density for maximum compaction

Question 3: What is the purpose of conducting an unconfined compression test on a soil sample?

Which action should you take?

Choose only one option

To estimate the permeability of the soil

To determine the unconfined compressive strength

To measure the plasticity of the soil

To assess the settlement behavior of the soil

Question 4: When performing a site analysis, how does soil compaction influence foundation settlement in cohesive soils?

Which action should you take?

Choose only one option

Lower compaction decreases soil strength

Higher compaction leads to reduced settlement

Compaction has no impact on settlement

Higher compaction increases settlement

Question 5: What is the main purpose of conducting a seismic site classification for foundation design in earthquake-prone areas?

Which action should you take?

Choose only one option

To assess groundwater depth and soil type

To identify structural vulnerabilities and adapt the building design

To reduce moisture levels in the soil

To determine the site-specific seismic hazard level and design accordingly

Question 6: What role does soil texture (sand, silt, clay) play in settlement and compaction analysis for foundations?

Which action should you take?

Choose only one option

Soil texture only influences the aesthetic characteristics of the foundation

Soil texture affects the compaction characteristics and the rate of settlement, with coarse-textured soils generally experiencing less settlement

Soil texture has no impact on settlement but affects the soil's permeability

Clay soils have less settlement than sandy soils, even without compaction
