3 0 0 3
OBJECTIVE:
At the end of the course student is expected to identify the problematic soil and suitable
suggest remedial measures to improve their behaviour.
UNIT I PROBLEMATIC SOIL AND IMPROVEMENT TECHNIQUES 8
Role of ground improvement in foundation engineering – methods of ground improvement –
Geotechnical problems in alluvial, lateritic and black cotton soils – Selection of suitable ground
improvement techniques based on soil conditions.
.
UNIT II DEWATEREING 10
Dewatering Techniques - Well points – Vacuum and electroosmotic methods – Seepage
analysis for two – dimensional flow for fully and partially penetrated slots in homogeneous
deposits (Simple cases only).
UNIT III INSITU TREATMENT OF COHESIONLESS AND COHESIVE SOILS 10
In-situ densification of cohesion-less soils and consolidation of cohesive soils: Dynamic
compaction Vibroflotation, Sand compaction piles and deep compaction. Consolidation:
Preloading with sand drains, and fabric drains, Stone columns and Lime piles-installation
techniques only – relative merits of above methods and their limitations - stabilization of
expansive soils.
UNIT IV EARTH REINFORCEMENT 9
Concept of reinforcement – Types of reinforcement material – Reinforced earth wall –
Mechanism – simple design - applications of reinforced earth. Role of Geotextiles in filtration,
drainage, separation and road works.
UNIT V GROUT TECHNIQUES 8
Types of grouts – Grouting equipments and machinery – injection methods – Grout monitoring
– stabilization with cement, lime and chemicals.
