 INTRODUCTION

The article Soil improvement and reinforcement – Treatments without additives [C 255] developed the various techniques for improving soils without additives, by mass densification of powdery or cohesive soils. This article describes techniques for reinforcing soils with flexible or rigid inclusions.

Each of the two chapters first presents the technique under study, then defines the fields of application. An analysis of the advantages and limitations of the two techniques enables the reader to compare them and make the right technical – economic choice. The essential elements for good design and precise dimensioning of geotechnical structures are indicated. The execution and works section is followed by advice on the monitoring, inspection and instrumentation of structures, essential in the complex field of soil reinforcement techniques.
