Garrett High School Geotechnical Engineering Worksheet

Answers are already provided. I just need a magical finishing touch!!!!!!This is what my professor said.
Number 2: -5 You aught to mention skin friction that aided the piles to support the load. I
mentioned during the Webinar that the video can be found on Canvas. You are also expected to
watch the recorded webinar if you missed it.
Number 3: -5 Which state?
Number 5: -5 Special attributes are from the notes from University of UTAH in the module. 1.
Soil is Heterogeneous 2. Soil is Non Linear 3. Soil is Non Conservative 4. Soil is an-isotropic.
Number 6: -5 You aught to plot it on a semi-log graph, please watch the videos on several
examples of the same problem.
Number 7: -5 You aught to plot it on a semi-log graph, please watch the videos on several
examples of the problem.
can you plz redo it and ill send you more matrials

Question 1
Give details of examples of some geotechnical projects as discussed in the class, cite the
experience from any construction site you have ever visited, if you have not visited any, try to
visit one and take pictures.

Please watch the video in the link below and comment on the application of geotechnical
engineering in constructing this gigantic structure on the ocean.

Question 3
Contact the Board of Registration for Professional Engineers in your state or province and find
out the requirements for becoming a registered professional engineer. Start planning to take the
FE examination when it is given in your area next year. Please site your source of information.
Question 4
1
Discuss about the learning experience a typical Geotechnical Engineer will gain from the Japan
Earthquake and Tsunami that occurred in 2011 (Make sure you give detailed engineering
information about the earthquake and Tsunami as well diagrams and pictures).

Geotechnical Engineering
Question 1
Geotechnical investigations are undertaken to acquire information on the physical properties of
rocks and soil around a site to acquire for the purpose of design of earthworks and foundations of
proposed structures and foundations of buildings. This investigation otherwise known as site
investigation helps to repair distress and check on the subsurface conditions.
Question 2
The different properties of soil such as shear strength and permeability influence the structures
and strengths of water barrier. As such, to the importance of oceanic constructions geotechnical
engineering helps to culminate the drawbacks and disaster probabilities such as tsunamis and
earthquakes. Eventually, helping to reduce the time and magnitude of impact to different natural
disasters such as high water currents and earthquakes ensuring that the structures are strong.
Question 3
The requirements of becoming a profession engineer according to the board of engineers
California state requires one to pursue an educational degree from one of the registered
universities in the state. This guarantees that one has fulfilled the core curriculum requirements
of becoming a profession. However, one is required to take a licensing examination that confirms
his skills and applicability of principles in a real scenario. The exams are normally done after
completing the educational and theoretical studies.
Question 4
Because of Japan’s long history in earthquakes and Tsunamis the country has several structures
that have been built to protect the cities and people within the region. However, due to the strong
magnitude earthquake and tsunami in 2011 the country’s break waters stood no chance to the

magnitude. This presents geotechnical lessons on the importance of rock and soil foundations to
resistant of natural disasters.
For instance, the break waters constructed and the bay entrance in Kamaishi they measure 63
meters deep with a solid foundation on the rocks. Additionally, the break waters are 670 and 990
M long. The importance of such strong, firm and long structures in protection from high
magnitudes is that it delays the magnitude and time of arrival of a disaster. Giving the nation
more time to respond to the disaster and rescue people.
Question 5
Soil has and continues to be one of the most important aspects of major constructions projects.
Contributing to major sites foundations and materials of construction, the selection of such an
important aspect of engineering is dependent on the following: specific gravity, density, shear
strength, density, compaction, consolidation and permeability.
In addition, geotechnical engineering has four main branches that relates to the close importance
of soil. These are; climate, water resource, geological and environmental engineering.

Determine the percentages of sand, silt, clay and gravel using the MIY system
Percentage passing sieve = 4[4.75] =100%
Gravel= [100-100] %
= 0%
Percentage passing sieve = 200* 0.75 = 80%
Fines = 80 %
Sand = 100% – 0%- 80%
= 20%
