Vacuum Consolidation Method (VCM) is one of the effective ground improvement treatments applied in construction works in Viet Nam recently. However, its affected area impacts to the adjacent works has not been studied in detail and standarised, leading to unexpected incidents. This paper proposes a method to determine the affected area of vacuum consolidation method then propose solutions to protect works. The result was demonstrated at approach road of Vam Sat 2 bridge project, located in Can Gio district, Ho Chi Minh city and shows high efficiency, ensuring economic-technical factor.

Clay Deposits

Vacuum preloading of clay deposits is becoming an increasingly popular ground improvement technique. Although many studies have been reported in literature, the mechanism of vacuum preloading is still not properly understood. Soil under vacuum preloading is expected to undergo an inward lateral deformation, therefore the influence of lateral deformation on volumetric strain requires further analysis. This paper addresses this aspect through laboratory studies on reconstituted samples of kaolinite. The Rowe cell apparatus was modified to measure lateral deformation under various states of stress because lateral and vertical deformation of soil depends on its state of stress and associated lateral pressure. A method for predicting the volumetric and lateral strains under vacuum consolidation is proposed and then applied to two case studies in China.

AbstractLa Parrilla is a tungsten and tin mine located in western Spain. The tailings facility has a total capacity for 3 Mm3 and will be executed in four different phases. The main constraint for the design and construction of the tailings dam is that it has been constructed over an existing one from the 1980s. The construction activities involved removal and substitution of the old tailings from the southern portion of the facility, ground improvement with gravel columns over an area of about 10,000 m2, and construction of the dyke’s dam. This article describes the main design and construction aspects, including monitoring, until the dam’s completion in June 2019.
