Problems solved by technology

The current safety assessment is usually carried out in the stage of project demonstration or program review. Dynamic assessment is rarely carried out during the construction process. The site conditions of tunnel excavation and blasting are constantly changing. Construction programs such as blasting and support are dynamic, and safety risks are dynamically changing. Security assessment is difficult to implement dynamically
The security assessment operation is relatively complicated, and usually can only be carried out by experts or professionals

Abstract

The embodiment of the invention provides a risk assessment method and a risk assessment device, so as to solve technical problems that during a tunnel blasting project in the prior art, qualitative assessment is mainly carried out through an experienced person and an expert, the qualitative assessment is mainly subjective judgment and qualitative analysis, quantitative analysis is lacked, and thus, the stability and the accuracy of an assessment result are poor. According to the risk assessment method and the risk assessment device provided by the invention, after the identity of a user passes verification, basic events for project assessment inputted by the user are received, the risk values of the basic events are calculated quantitatively, and according to the risk values and the weight values of multiple basic events and a grahame assessment method and a fault tree analysis method, the risk value of the assessment project is acquired, and according to the risk value of the assessment project, the assessment result of the assessment project is acquired. Thus, the technical effects of quantitatively calculating the risk value of the assessment project and acquiring the risk assessment result according to the multiple basic events of the assessment project are achieved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a risk assessment method and device. Background technique [0002] The security risk assessment in the prior art is mainly through qualitative assessment by experienced personnel and experts, mostly subjective judgment and qualitative analysis, and lacks quantitative analysis. The current safety assessment is usually carried out in the stage of project demonstration or program review. Dynamic assessment is rarely carried out during the construction process. The site conditions of tunnel excavation and blasting are constantly changing. Construction programs such as blasting and support are dynamic, and safety risks are dynamically changing. Security assessment is difficult to implement dynamically. The security assessment operation is relatively complicated, and usually can only be carried out by experts or professionals.
