Ứng dụng phương pháp HIBER-HUGHES-TAYLOR-Α phân tích kết cấu tháp điều áp chịu tải trọng động

Abstract

Pressurized tower is one of the important items in the hydropower plant system and especially for small hydropower projects, mainly using the type of path exploitation. The structure of the imposing control tower and the water level in the tower is constantly changing to ensure stable operating conditions of the pressure line, so the bearing conditions are relatively complicated. The main research contents of this paper apply HHt-α method to study the impact of water level fluctuation on the pressure regulator tower. Thereby determining the stress field in the structure of the pressurized tower structure changes over time in response to changes in the water level in the tower according to the actual conditions in order to have appropriate construction behavior to ensure economic conditions and Technology.
