ADVANCED GEOTECHNICAL ENGINEERING
CE 76512

Course Objectives:
The objective of the course is to provide the student with the concept and the tools that can be used to incorporate in the field of geotechnical engineering. The course includes the advanced techniques that are not dealt in the courses of soil mechanics and foundation engineering.

1. Scope of Advanced Geotechnical Engineering
   (2hours)
1. Field of application of advanced geotechnical engineering
2. Different sectors of geotechnical engineering
2. Field Instrumentation and Monitoring
   (12hours)
1. Types of field measurements and their uses
2. Monitoring displacements of foundations and structures: vertical and horizontal displacement
3. Monitoring slope/rock mass movement: slope movement using borehole extensometers, inclinometers and tiltmeters: rockmass displacement in underground excavations etc. using optical, electro-optical methods of borehole extensometers
4. Monitoring pressures/loads in earth: walls and structures; monitoring pressures in the body of earth structures
5. Monitoring ln-situ stresses in rock; hydraulic fracture techniques, direct stress measurement techniques; and borehole methods
6. Monitoring pore water pressure: methods based on various types of piezometers, selection of piezometers to suit the ground condition
7. Recording and data handling
3. Geosynthetics
   (9hours)
1. Types of geosynthetics
2. Application of geosynthetics drainage, filtration reinforcement and separation
3. Design consideration: physical properties, mechanical/hydraulic durability requirements
4. Construction requirements: site preparation, selection of equipment, placement and compaction requirements
4. Anchors, Rock Bolts and Shotcrete
   (9hours)
1. Application and types of anchors and rock bolts
2. Design criteria: safety against uplift, overturning, tangential displacement, shear failure and caving in
3. Installation: drilling, insertion, grouting (anchoring) stressing and final grouting
4. Mechanism of load transfer in anchors
5. Testing of anchors
6. Protection from corrosion
7. Selection of materials and mix design of shotcrete
8. Engineering properties of shotcrete
9. Placement of shotcrete
5. Grouting
   (4hours)

4. Planning of grouting works
5. Selection of grouting materials
6. Grouting methods
7. Control of grouting works
6. Geotechnical Earthquake Engineering
   (9hours)
