10 Questions
Define the role of a foundation in a structure.
A foundation is an element of a structure that takes and distributes loads safely through the soil.
Explain the concept of stress distribution in a foundation.
The foundation spreads the load into a larger area, reducing the pressure imposed on the soil underneath it.
What is the purpose of a good foundation in relation to settlements?
A good foundation prevents or reduces the effect of all types of settlement, ensuring it is not harmful to the structure.
What is the condition that must be met for the pressure imposed on the soil to be acceptable?
The pressure imposed on the soil must be less than the allowable bearing capacity of the soil.
Why is it important to consider the condition mentioned in the previous question?
It is important to consider the condition to ensure the foundation does not exceed the capacity of the soil and lead to failure.
What is subsurface exploration and why is it important in the field of geotechnical engineering?
Subsurface exploration is the process of identifying the layers of deposits underneath a proposed structure and their physical characteristics. It is important in geotechnical engineering as it helps in selecting a suitable foundation type and depth, evaluating load-bearing capacity, estimating settlement, identifying potential foundation problems, determining the groundwater table, predicting lateral earth pressure, and establishing construction methods for changing subsoil conditions.
What are the main objectives of subsurface exploration?
The main objectives of subsurface exploration are: 1) Selecting a suitable type and depth of foundation, 2) Evaluating the load-bearing capacity of the foundation, 3) Estimating the probable settlement of a structure, 4) Determining potential foundation problems, 5) Determining the groundwater table, 6) Predicting the lateral earth pressure for structures, and 7) Establishing construction methods for changing subsoil conditions.
Why is subsurface exploration necessary for additions and alterations to existing structures?
Subsurface exploration is necessary for additions and alterations to existing structures to understand the underlying soil conditions and assess the feasibility and potential challenges of the proposed changes.
What information does subsurface exploration provide to geotechnical engineers?
Subsurface exploration provides geotechnical engineers with information about the layers of deposits, physical characteristics of the soil, suitable foundation types and depths, load-bearing capacity, settlement estimates, potential foundation problems, groundwater table, lateral earth pressure predictions, and construction methods for changing subsoil conditions.
How can subsurface exploration aid in the selection of a suitable foundation for a structure?
Subsurface exploration provides information about the soil conditions, such as the type and strength of the deposits, which helps in selecting a suitable foundation type and depth based on the load-bearing capacity and settlement requirements of the structure.
