Abstract:

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.
