Abstract

Mumbai is the region consisting of soft compressible marine clay deposits. There are several construction problems on such soils and thus ground improvement need to be carried out. Vertical drains is generally preferred technique as accelerated settlement is achieved during the construction phase itself. The concept of vertical drains is based on three dimensional consolidation as described by Terzaghi (1943). Based on this concept, a settlement programme is being developed and an attempt is made to determine the field to laboratory coefficient of vertical consolidation ratio by methods proposed by Taylor and Asaoka (1978) for this region by considering the case studies namely 1.) Mulund Airoli Bridge approach embankment 2.) Palm Beach Marg. Based on this ratio, the rate of consolidation and time required for consolidation in the field can be determined knowing the consolidation parameters.
