chuyển dịch tiêu chuẩn.The construction standards system in Vietnam is being improved to meet the requirements of state management and activities in the construction sector amid Vietnam's economic integration with the world. The transition of foreign standards into the national standards is underway, including standards related to foundation calculations. The translated standards will be used concurrently with the existing standards according to the prescribed roadmap. Each standard has its own characteristics built upon different theoretical frameworks, such as calculation methods, posing challenges for consistency and uniformity within the standards system. Therefore, this study synthesizes, compares, and analyzes the differences among standards related to foundation calculations. The research results indicate that there are differences between the standards, leading to variations in calculation outcomes. These differences create difficulties in practical standard application. Preliminary proposals are also presented for a unified standards system in foundation calculations.Keywords: Standard systematization
