Abstract

Preloading with prefabricated vertical drains (PVDs) is one of the most successful methods for improvement of soft soils settlement. A preloading project is described in the southwest of Iran near the Persian Gulf, in which well-planned instrumentation was used. The purpose of the project was placement of an 8 m embankment with installation of PVDs to accelerate the consolidation of subsoil for construction of a concrete water tank, 100 m × 150 m with total volume of 100 000 m3. The thickness of soft soil was about 15 m. This paper presents results of soil instrumentation to measure dissipation of excess pore pressure, differentiating settlement in different soil layers and a comparison of t..
