Description

The Soils Engineering for Practical Applications Workshop is a basic geotechnical course which will provide practical knowledge for both generalists and those needs to upgrade their knowledge in geotechnical design field. Each theoretical concept presented will be linked to practical applications in the geotechnical engineering area.

The purpose of this workshop is to familiarize participants with the application of basic soil mechanics principles to the design and analysis of simple geotechnical structures including: earth works , bearing capacity of shallow foundations, soil retaining structures and slope stability. In addition the theory of consolidation and practice of site or ground investigation will be discussed.

The course objective is to impart to the participants the necessary knowledge and skills to determine the minimum level of geotechnical effort needed on an engineering project and /or how to deal with geotechnical information/personnel on a given project.

The participants will develop knowledge and appreciation of geotechnical activities in all project phases and understanding of different soils and how they behave.

No prior knowledge of the subject is required; the course content follows a simple starting level into advanced level that will be built step by step in class. The concepts presented in each lesson are concise and specifically directed at a particular practical operation in the geotechnical design process.

Recommendations are presented on how to efficiently layout borings, how to minimize approach embankment settlement, and how to transmit design information properly to construction. Basic examples are included in several lessons for hands-on knowledge.

Objectives

Course objective is to impart to the participants the necessary knowledge and skills to determine the minimum level of geotechnical effort needed on an engineering project. A high level of interaction between the expert instructor and the students will be used to facilitate the development of knowledge and skills in basic geotechnical concepts and analyses. Upon completion of the course, the participants will have demonstrated learning of the following:

  • Knowledge of the minimum level of geotechnical input in various project phases of an engineering project,
  • Knowledge of the equipment and procedures used to implement a subsurface investigation of soil and rock conditions,
  • Knowledge of the basic soil test procedures and application of soil test results,
  • Knowledge and basic skills in procedures used for determining bearing capacity and settlement of spread footing foundations,
  • The interpretation of field and laboratory test data and derivation of meaningful parameters for geotechnical design * Knowledge of the format and minimum content of an adequate foundation report.
  • Methodologies of soil classification and property testing, basics of clay mineralogy
  • Concepts of pore water pressure, effective stress and capillarity and their implications on soil behaviour including swelling, shrinkage and frost action.
  • One-dimensional settlement and consolidation
  • Concept and measurement of soil shear strength
  • Design implications of consolidation, flow, settlement and shear strength and how the basic concepts can be applied in engineering practice.
  • Introductory analysis of lateral earth pressures

Target Audience

This course is geared to practicing engineers, technicians and technologists who routinely deal with soils and foundations problems. No theoretical background is required in soil mechanics or foundation engineering although computational skills are necessary for the design sessions.

The categories of personnel at all engineering levels who could benefit from this workshop include drillers, Non-soils engineers , Industry tech/sales, representatives , Public works professionals , Engineers-in-training, Project engineers and managers, Architects and landscape architects , Geologists and earth scientists , Civil and other engineers, geotechnical, bridge design, highway design, structural engineers, construction engineers, contractors, owners, or any professional involved in the design, construction, inspection, testing, maintenance and specification of foundations. The greatest impact will be achieved by convincing structural, design, and construction engineers to use procedures from this course as a guide for routine geotechnical work. One of the major benefits of this course is to give engineers an appreciation of activities outside their specialties that influence, or are influenced by, the work of the geotechnical engineer.

Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at gic@gic-edu.com for Special Group & Corporate Rates for one or more participants.

We could offer any of our courses at a location of your choice and customized contents according to your needs, please contact us at : inhouse@gic-edu.com or click here  to submit an online request.
