Abstract

Abstract: It is a common practice for soil improvement methods in residential areas to strengthen only soils under the buildings. Therefore, differential settlement after construction might occur and even result in the cracking and/or tilting of buildings. This paper presents the results of a Vacuum Combined with Water Covered Preloading method for the entire site of a proposed residential development. Both theoretical and practical aspects of this technique are discussed in the paper. It is concluded that this method is successful in minimizing potential differential settlement.

Key words: Vacuum Combined with Water Covered Preloading, Soft Soil Improvement, Geotechnical Design and Construction
