Problems solved by technology
The disadvantages of this invention are: it only evaluates a certain side slope, and it cannot reflect the strength of the rainstorm disaster risk in the section, and it does not consider the structural characteristics of the tower foundation when it is used for the evaluation of the foundation slope of the transmission line tower. Information such as stratum litholog

Embodiment Construction
[0027] Below, the embodiments will be further described in conjunction with the accompanying drawings.
[0028] like figure 1 As shown, a kind of risk assessment method embodiment of the section transmission line pole tower foundation slope rainstorm disaster that the present invention proposes, comprises the following steps:
[0029] (1) Establish a comprehensive table of control factors for rainstorm disasters on the foundation slope of transmission line towers:
[0030] Analyzing the influencing factors of rainstorm disasters and determining the controlling factors are the first steps in carrying out risk assessment of rainstorm disasters.
[0031] There are quite a lot of influencing factors of the rainstorm disaster, and the determination of the control factors will fully consider the characteristics of the foundation slope of the transmission line tower, the difference of the section, and the practicality and economy. Geomorphic information (according to the longitude ...

The invention relates to an assessment method for rainstorm disaster risks of sectional power transmission line pole-tower foundation slopes, and the method comprises the following steps of acquiring control factors of the rainstorm disaster risks of the pole-tower foundation slopes, and quantizing and normalizing the control factors; establishing a mapping relation between the control factors and a rainstorm landslide accident rate by utilizing an improved BP (Back Propagation) network and adopting disaster statistics and artificial rainfall slope erosion test results as training samples, and acquiring a risk assessment mathematic model; and acquiring the rainstorm landslide risk grade of each slope relative to a whole line by adopting the calculated average rainstorm landslide accident rate value of the whole-line foundation slope as a benchmark value, acquiring a weight vector of each section in terms of percentage for the slope at each risk grade by utilizing an improved layering analysis calculation program, with consideration of different influences of the slope at each risk grade on the rainstorm disaster risks, calculating the weight vector of the slope at each risk grade for the rainstorm disaster by continuously adopting the improved layering analysis calculation program, and finally synthesizing the weight vectors of all layers from top to bottom by utilizing a computer to obtain the risk assessment result of each section.
Description
technical field [0001] The invention relates to a method for assessing the risk of rainstorm disasters on the foundation slope of a section transmission line tower, which is applicable to the risk assessment of the landslide section of the foundation slope of a high-voltage transmission line, an ultra-high voltage transmission line and an ultra-high voltage transmission line. Background technique [0002] The transmission line is an important part of the power grid, and the safe and stable operation of the transmission line directly affects the stability of the power grid and the reliability of power supply. Due to the erosion of soil and water caused by heavy rain, generalized landslide disasters such as slope erosion, landslides, and landslides closely related to it occur from time to time, endangering the safety of power transmission line towers, and even causing the line to fall and break. Therefore, preventing transmission line tower foundation side slope rainstorm disa...
