Embodiment Construction

[0041] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] This embodiment takes the regional landslide geological disaster risk classification evaluation method of power grid engineering as an example, as follows figure 2 As shown, the power grid engineering regional landslide geological disaster risk classification evaluation method provided by the embodiment of the present invention selects and classifies landslide influencing factors and power grid factors, and determines the risk and final classification by weight analysis of landslide influencing factors and power grid factors , including the following steps:

[0043] 1. Determine the factors affecting landslides and grade them; factors affecting landslides include: fault structure, landform, terrain slope, stratum lithology and rainfall factors. Each factor is graded and quantified by corresponding indicators. The...

Abstract

The invention provides an evaluating method for the regional landslide geological disaster risk grading of a power grid project. Landslide influence factors and power grid factors are selected and graded, and through the weight analysis of the landslide influence factors and the power grid factors, risk and final grading are confirmed. Compared with the prior art, the evaluating method provided by the invention highlights the importance of the power grid as a stricken main body in the risk, and accurately reflects the risk of actual power grid landslide disaster.

Description

technical field [0001] The invention relates to a method for grading and evaluating the risk of geological disasters, in particular to a method for grading and evaluating the risk of regional landslide geological disasters in power grid engineering. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] With the rapid development of transmission line engineering construction, landslide disasters have caused catastrophic damage to power grid facilities, causing high post-disaster recovery and r...
