Code

CE-GEO1

Version

2.0

Offered by

Civil Engineering

ECTS

5

Prerequisites

For exchange/transfer students:
General admission requirements and basic knowledge about soil mechanics/geotechnical engineering.

Main purpose

The purpose of the course is to acquire knowledge of the execution of construction pits.

Knowledge

Following completion of the course, the student has knowledge of:
– Execution of construction pits
– Advantages and disadvantages of different types of retaining walls
– Execution of supports for retaining walls
– The use of shoring boxes
– Critical gradient and the risk of base failure
– Different software to support analyzes of deep excavation

Skills

After completion of the course, the student must have the skills to:
– Describe possible ground water lowering system
– Determine when to use shoring boxes
– Calculate the critical gradient and check if there is a risk of base failure
– Determine the safety against slope failure

 

Competences

After the course, the student will be able to apply knowledge and skills to:
– Analyze deep excavations, e.g. evaluate the most suitable type of retaining wall, supports and groundwater lowering system for deep excavations
– Evaluate risks of constructing deep excavations
– Design and plan ground water lowering systems
– Design slopes to ensure their stability

Topics
