After successful completion of the course, students are able to...

• name basic selection factors for special ground engineering techniques,  
  
• differentiate the topics 'system-related risks' and 'ground risks',    
• name basic aspects of the most important special ground engineering techniques:
• diaphragm walls, bored piles, driving piles, anchor technology, injection technology, jet blasting, soil improvement,
• explain in detail the 'prestressing principle of anchors,
• categorize anchor elements according to the relevant standards,
• explain regulations of the contractual provisions 'impermeable diaphragm walls' in detail,
• distinguish methods for pile load tests,
• calculate creeping of piles and anchors.

Overview on special ground engineering techniques considering recent developments: basics, design and execution, amongst others diaphragm walls, bored and displacement piles, retaining walls (prestressed anchors, soil nailing, tension piles), jet grouting

Using examples from the practice of special ground engineering, students will be introduced to special ground engineering techniques in a vivid lecture.

Lecture mode in winter semester 2022:
The course will be held in presence in the winter semester 2022. In case the holding of lectures in presence is no longer permitted due to the requirements of the Federal Government or the TU Wien, a change to an online-mode is carried out.

Examination mode in winter semester 2022:
Written exams will be held in presence. In case the holding of examinations in presence is no longer permitted due to the requirements of the Federal Government or the TU Wien, a change to "written online paper exams" is carried out. Examination duration and assessment scheme remain unaffected. In this context, please refer to the COVID-19 Distance Examination Regulations of the Research Unit of Ground Engineering, Soil and Rock Mechanics.

The written examination (incl. calculation and sketch) checks whether the students have achieved the defined learning outcomes.
