Abstract

Awedge base foundation comprises the wedge blocks made from soft soil, cement and additive. The blocks are arranged side by side and filled with sand in the void between them. The foundation top is covered with a sheet of tensile geotextile. This foundation was proposed since 2014 and onging studying its application for sea dykes in Mekong river delta. The establishment of the new formula to calculate the wedge base foundation bottom stress is extremely significant for evaluating the ground stability; however, it has not been established so far. This article introduces the content, research method and the result gained in the establishment of the above-mentioned formula to apply it to Mekong river delta sea dykes.
