CE1014 GROUND IMPROVEMENT TECHNIQUES 3 0 0 100
OBJECTIVE
After this course, the student is expected to identify basic deficiencies of various soil deposits and he/she be in a position to decide various ways and means of improving the soil and implementing techniques of improvement.
1. INTRODUCTION 9
Role of ground improvement in foundation engineering - methods of ground improvement –
Geotechnical problems in alluvial, laterite and black cotton soils -Selection of suitable ground improvement techniques based on soil condition.
2. DRAINAGE AND DEWATERING 9
Drainage techniques - Well points - Vaccum and electroosmotic methods - Seepage analysis for two dimensional flow-fully and partially penetrating slots in homogenous deposits (Simple cases only).
3. INSITU TREATMENT OF COHESIONLESS AND COHESIVE SOILS 9
Insitu densification of cohesionless and consolidation of cohesive soils -Dynamic compaction and consolidation - Vibrofloation - Sand pile compaction - Preloading with sand drains and fabric drains – Stone columns – Lime piles - Installation techniques only - relative merits of various methods and their limitations.
4. EARTH REINFORCEMENT 9
Concept of reinforcement - Types of reinforcement material - Applications of reinforced earth – use of Geotextiles for filtration, drainage and separation in road and other works.
5. GROUT TECHNIQUES 9
Types of grouts - Grouting equipment and machinery - Injection methods - Grout monitoring – Stabilisation with cement, lime and chemicals - Stabilisation of expansive soils.
