CE6012                     GROUND IMPROVEMENT TECHNIQUES                  L T P C 3 0 0 3

OBJECTIVES:
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 - Design.

UNIT III           INSITU TREATMENT OF COHESIONLESS AND COHESIVE SOILS                   10
Insitu 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 – simple design - relative merits of above methods and their limitations.

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, road works and containment.

UNIT V           GROUT TECHNIQUES                                                                                            8
Types of grouts – Grouting equipments and machinery – injection methods – Grout monitoring –
stabilization with cement, lime and chemicals – stabilization of expansive soil.
TOTAL: 45 PERIODS
OUTCOMES:
Student will be in a position to identify and evaluate the deficiencies if any in the deposits of a project area and capable of providing alternate methods to improve its character suitable to the project so that the structures built will be stable and serve.
