The invention discloses an improved power transmission line high-position landslide risk evaluation system and method, and the method comprises the steps: firstly building a power transmission line high-position landslide stability evaluation factor, carrying out the quantitative evaluation of the evaluation factor, and determining the weight of the evaluation factor, thereby building a power transmission line high-position landslide stability evaluation model and a grading method, and further establishing an iron tower exposure degree evaluation index and a grading method, and finally establishing a power transmission line high-position landslide risk evaluation method considering landslide stability and iron tower exposure degree. According to the method, the landslide stability and the iron tower exposure degree are jointly used as power transmission line high-position landslide risk evaluation indexes, the stable state of the landslide is considered, the spatial position relation between the landslide and the iron tower is also considered, and the technical effects that the evaluation result is more targeted for guiding power transmission line geological disaster prevention and control and the result is more accurate are achieved.
Description
technical field [0001] The invention relates to the technical field of risk assessment of landslide hazards of power transmission lines, in particular to an improved risk assessment method for high-level landslide disasters of power transmission lines. Background technique [0002] As the country's requirements for smart grids and green grids gradually increase, the demand for construction of high-voltage and longer transmission distance transmission lines is also increasing. More and more transmission lines must pass through mountainous areas prone to geological disasters. Mountainous transmission lines The threat of geological disasters is also becoming more and more prominent. [0003] At present, the landslide risk assessment of transmission lines is mainly based on the requirements of the "Technical Requirements for Geological Hazard Risk Assessment (Trial)", through the on-site investigation of the landslide body, selecting factors such as topography, geology and human...
