Ground Improvement Techniques – Classification, Case Studies and Trends
(30 August -09 September, 2016) Department of Civil Engineering, NIT WARANGAL
1. Overview
Ground improvement is one of the basic requirements of many civil engineering construction projects. Improving the ground permits construction on problematic soils by changing their characteristics and strength. With the introduction of Japanese high speed railways (Shinkansen) in India, ground improvement will play a significant role in the construction and infrastructure development in India.
This course focuses on the principles of various ground improvement techniques developed in Japan, Asia and the rest of the world. The course will encompass the understanding of the problems facing geotechnical researchers and engineers working in the field of ground improvement, and will also cover the recent advances in the techniques available to them. The course contents consist of three parts. Part I focuses on the approaches for ground improvement geosystem dividing each techniques in to various groups and mechanics involved in each techniques. Part II describes many case histories from Japan and other Asian countries based on the tutors‘ experiences of working in various ground improvement projects and their implementation. Part III focuses on the new applications and trend of the ground improvement geosystem including recycling, geo-environmental consideration and preservation of the world cultural heritage.
This course targets the beginners and the intermediate level practitioners who are dealing with geotechnical construction projects or who have interest in the development and application of ground improvement techniques. Engineers and researchers will find it helpful in developing, advancing and applying the techniques in the field.
In this course, ground improvement techniques, their theoretical background, methods adopted in a particular situation and accomplishment of the projects will be described in an easily understandable way. This course helps students, researchers and engineers to understand what is ground improvement, principles of the improvement methods considering the geological and geotechnical background, how they are executed in the site, basis of selection of a particular ground improvement technique in a project, and the cost-performance of such methods, etc.
The course will be delivered by expert who had many years of practical and consulting experiences as well as experiences on research, development and, execution of ground improvement projects in Japan and other Asian countries.

2. Objectives

The primary objectives of the course are as follows:

i) Explain the mechanics of ground improvement technique and mechanism involved including the important factors that will help engineers in judging and adopting a particular technique in the fields.
ii) Describe many case histories from Japan and other countries of the world. Numerous case studies will help to understand how the new and improved methods have actually been applied over a wide variety of ground conditions.
iii) Contribute to a better understanding of various existing ground improvement techniques, which will be described in a concise and easily understandable ways.
iv) Help students, engineers, researchers and practitioners gaining a firsthand experiences of ground improvement techniques through many case studies along with some example calculations
