Phân tích sức chịu tải và cơ chế phá hoại cọc đá ở đồng bằng sông cửu long

Abstract

Soft ground reinforced by stone column is one of the typical methods for soft ground improvement. Depending on the characteristics of geological structure, the load-capacity and economic efficiency of each type of construction, the most efective solution for soft ground reinforcement has been used. In this paper, the authors analyzed the load-bearing capacity of stone columns (single pile) for warehouse foundation in Mekong Delta by widely used methods such as Vesic (1972), Greenwoood (1970), Vitkar (1973), Bachus (1983), and Plaxis 3D Foundation. These results were used to compare with those from the field static test. Based on the results of the study, the authors assessed the failure mechanism of the stone column when is subjected to the load applications.
