What caused the engineer to tear his maps and reports?
Answers
Answer:
Geotechnical report contents
Analysis of data given in report
Soil boring equipment
Recommendations for construction methods and slopes
Soil boring logs
Soil description (classification such as silty-sand)
Soil properties (hard, stiff, dense, loose, etc.)
Boring depth
Boring refusal
Blow counts
Soil moisture content
Soil dry density
Particle distribution curves (sieve analysis)
Atterburg limits (liquid limits and plasticity index)
Compaction test (optimum moisture for compaction)
Direct shear tests
Seismic velocity lines
Permeability
Learning Objective
This course introduces the student to the many components that make up a thorough Geotechnical report. The various observations and tests are explained so that an inference to the ground properties can be achieved. The Geotechnical report is a complex scientific document that can be confusing to even highly experienced people.
Owners, architects, engineers, and contractors must be able to understand the implications of the reports in order to achieve an on time, on budget and failure free project.
At the conclusion of this course, the student will learn:
That major projects usually have Geotechnical Reports.
How to interpret the Geotechnical report for consistency.
How to evaluate soils for embankment suitability.
How to determine the presence of ground water and how it will effect design and construction.
How to interpret seismic velocity diagrams for excavation methods.
To Understand that the Geotechnical Report is often a subjective opinion of an individual geologist.
Course Introduction
The Geotechnical report provides critical and vital information for the owner, architect, design engineer, and the contractor to use and evaluate. The owner wishes to assess the cost of the project foundation and earthwork. The structural engineer is responsible for the design of an economical but sturdy building foundation. The architect may be forced to arrange building layouts to accommodate varying soil conditions. The contractor wants to bid a competitive but realistic price for the excavation and embankment work. For these reasons, all the essential players have a personal stake in the Geotechnical report. All these players must be able to understand the ramifications of the soil study. A foundation failure of a major structure is measured in millions of dollars and ruined careers. It can even lead to loss of life, such as the Teton Dam failure. An ignorant or misinformed contractor can lose millions in unanticipated costs. Such mistakes often lead to major lawsuits that drag on for years and cost everyone except the lawyers. Being able to understand and analyze the Geotechnical report to avoid costly mistakes is in the best interest of all the project players.
