Simulation method for short and long legs and foundations of power transmission tower

Abstract

The invention provides a simulation method for short and long legs and foundations of a power transmission tower. The method comprises the steps of building a three-dimensional digital ground model in combination with measurement data by performing coordinate projection correction and image fusion processing on high-resolution satellite images and a digital elevation model based on a three-dimensional GIS geographic information technology; generating a terrain TIN network around a tower position on a GIS platform; generating high-precision contour line data; and drawing an accurate tower foundation section graph or tower position terrain graph. According to the method, the terrain situation of the tower position can be intuitively displayed, so that the workload of field work personnel is reduced; the high-precision contour line data is provided, so that designers can comprehensively view the tower position terrain without going to the scene; the function of configuring comprehensive short and long legs and low and high foundations of a power transmission line of a mountainous region in batches can be realized, so that the design workload is reduced and the design efficiency is improved; and an efficient and reliable simulation basis is provided for the arrangement of the power transmission line in the mountainous region, so that reliable running of a power grid is ensured.

Description

technical field [0001] The invention belongs to the field of power transmission tower simulation, and in particular relates to a simulation method for the long and short legs and foundation of a power transmission tower. Background technique [0002] In order to implement the design concept of "environmentally friendly transmission lines" of the State Grid Corporation of China, when the soil conditions are suitable, the lines in mountainous areas, hills and other areas adopt the design mode of using all-round long and short legs in conjunction with high and low foundations. Traditional engineering design needs to first conduct field survey and positioning of the project, measure and draw tower base cross-section and tower topographic map, and then carry out engineering internal design; and the design of the length and length of the transmission tower and the basic configuration work require electrical, surveying, and structural three-dimensional work. The professions coopera...

Problems solved by technology

[0003] At present, the design of the length and length of the transmission tower and the basic configuration work generally need to be measured in the field, and designers need to go to the site to measure the terrain and landform around the tower, so it is impossible to achieve efficient transmission line design, and at the same time, it is impossible to guarantee the length of the transmission tower and the foundation. design accuracy
