Learning outcomes

Objective of the course:
- To gain a basic knowledge about the technologies of special foundations (piles, micropiles, ground anchors, grouting, jet grouting, etc.) and soil improvement (deep soil mixing, stone columns, etc.).
- To gain a basic theoretical knowledge about the design of shallow and deep foundations, deep excavation including their dewatering and stabilization elements (ground anchors, struts) according to Eurocodes.

The outcome of the course is to provide of technologies of special foundations and their adequate choice for given geotechnical conditions. Design and assessment of selected geotechnical structures (shallow foundations, piles, retaining walls, deep excavation and building pits including dewatering). Learning to use GEO5 to solve selected geotechnical problems.

Prerequisites

Types of foundation soils, properties of soils, limit states theory, basic principles of structural mechanics, theory of strength and elasticity, structure design.

Corequisites

Risks at foundation of objects, risks at implementing of deep foundation pits shoring, environmental geotechnics, computational methods in geotechnical engineering.

Planned educational activities and teaching methods

The presented topic is practiced on credit examples including the parts individually discussed. Part of the exercise takes place in a classroom PC - application software for the solution of the problem. Teaching includes optional lectures, field trips and workshops held currently in various projects.
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Forms and criteria of assessment

Conditions of credit is to develope a final credit examples and satisfying attendance.
The exam will consist of written and oral part. Condition of the oral exam is a written test conditions.

Objective

To teach students how to design shallow and deep foundations for different geotechnical categories.
To provide students with basic knowledge about safe and economical design of foundation pit.
To acquaint students with modern foundation methods and subsoil improvement methods.
