Rolling stone disaster risk assessment method, device and system and storage medium

Abstract

The embodiment of the invention discloses a rolling stone disaster risk assessment method, device and system and a storage medium. The method comprises: acquiring rolling stone disaster pregnancy factors within a first preset area range; inputting the rolling stone disaster-pregnant factor into a pre-established statistical model, and obtaining a rolling stone source point and a probability valuecorresponding to the rolling stone source point; simulating a rolling stone path by using the physical model and taking a rolling stone source point as a starting point; calculating the length of therolling stone path in the second preset area; and according to the search radius, the rolling stone path, the length of the rolling stone path, the number of the rolling stone paths and the probability value corresponding to the rolling stone source point in the rolling stone path, calculating a risk index of rolling stone disasters in the second preset area. In this way, the purpose of accuratelymeasuring the rolling stone risk is achieved, and the higher the risk index is, the higher the risk of rolling stone disasters is.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of geological disaster risk assessment, and in particular to a method, device, system and storage medium for risk assessment of rolling stone disasters. Background technique [0002] Rolling stone is a kind of geological disaster widely distributed in the alpine and valley areas of our country. It has a wide distribution range, sudden occurrence and high frequency, and often causes losses to mountainous roads, railways, tunnels, houses and people. How to quickly, accurately and effectively obtain the source area of ​​the rolling stone disaster, the potential affected area of ​​the rolling stone disaster, and the quantitative risk assessment of the rolling stone disaster are important problems at present, which are related to disaster prevention and mitigation projects and urban and rural planning in areas prone to geological disasters. It can be seen that it is very important to analyze...
