Application of Prefabricated Vertical Drains (PVDs) for Improvement of Soft Clays—A Case Study
This article presents the application of Prefabricated Vertical Drains (PVDs) for the improvement of soft clays. Paper explains design considerations and the execution steps undertaken for the application of Prefabricated Vertical Drains (PVDs) with surcharge as a ground improvement technique. The case study is based on the warehousing project in Navi Mumbai, India. The paper represents how the time for consolidation can be reduced using the PVDs. A detailed study of strata present at the project site was done. Based on the detailed soil investigations and site feasibility, ground improvement using Prefabricated Vertical Drains (PVDs) with surcharge was proposed. This paper shows a detail design procedure and the field execution of PVD with surcharge method. The design shows how the spacing/length/surcharge height and other parameters were adopted and computed. Ground improvement was adopted nearly for an area of 44 acres. This case study is about one of the biggest ground improvement projects on soft clays in India. The field monitoring was done using various equipment such as settlement gauges and the vibrating wire piezometer. Pore water pressures were studied, and the shear strength was monitored after ground improvement using post in situ testing. Article shows the field observations and the results with the help of time vs settlement curves, pore water pressure reading, and the settlement of the soft clay layers.
