The invention relates to the technical field of power transmission line tower structure wind resistance design, particularly provides a power transmission line tower structure type selection optimization method and device, and aims to solve the technical problems that the calculation process of the conventional standard power transmission line tower inertia force wind vibration coefficient is complicated, and the efficiency for tower structure type selection optimization is low. The method comprises the following steps: calculating a displacement wind vibration coefficient of the power transmission line tower according to the average displacement and the displacement root-mean-square of the power transmission line tower; calculating the wind load of the power transmission line tower according to the displacement wind vibration coefficient of the power transmission line tower, and determining the downwind displacement value of the tower top of the power transmission line; adjusting the structural parameters of the transmission line tower until the ratio of the downwind displacement value of the tower top of the transmission line to the tower height meets the set rigidity index requirement; according to the scheme, the problems that the calculation process of the inertia force wind vibration coefficient of the power transmission line tower is complex, and the optimization efficiency of tower structure selection is low are effectively solved, and better applicability and higher efficiency are achieved.
Description
technical field [0001] The invention relates to the field of wind resistance design of transmission line pole and tower structures, in particular to a type selection optimization method and device for transmission line pole and tower structures. Background technique [0002] Wind load is an important control load in the design of transmission lines. Its calculation method is related to the economy, safety and reliability of transmission line engineering. The wind vibration coefficient is one of the most important parameters for calculating wind loads on towers. Lean wind-resistant design is of great significance. The wind vibration coefficient is divided into two types: the inertial force wind vibration coefficient and the displacement wind vibration coefficient. The current design code generally uses the inertial wind load method to calculate the tower wind vibration coefficient and is called the "inertial force wind vibration coefficient". The wind vibration coefficient o...
