Abstract

The invention relates to an embankment flood risk evaluation index system construction method, which comprises detailed steps and can quickly judge risk factors influencing embankment engineering safety by deeply analyzing the risk factors influencing the embankment engineering safety. A comprehensive and complete embankment risk evaluation index system can be established by comprehensively considering regional embankment characteristics and combining an embankment and flood risks. According to the method, an analytic hierarchy process is combined with a one-dimensional and two-dimensional coupling model, and risk comprehensive evaluation for the high-risk embankment section is facilitated. According to the method, a social and economic data statistics method and a flood loss assessment method of affected areas are deeply analyzed, and accurate flood influence analysis and loss assessment can be carried out on the areas.

Description

technical field [0001] The invention belongs to the field of emergency disaster prevention and relates to a method for constructing a risk evaluation index system, in particular to a method for constructing an embankment flood risk evaluation index system. Background technique [0002] In the past, to solve the problem of embankment safety, it mainly relied on engineering to build dams and strengthen slope protection. In recent years, dike engineering safety accidents have occurred frequently, causing heavy losses to the safety of people's lives and property, prompting people to re-examine the previous prevention and control ideas. Although the country has invested a lot of engineering construction and greatly improved the flood control standards of embankments, which has reduced the flood risk, but due to the complex mechanism of embankment engineering, many risks involved, large changes in time and space, and the close relationship between various factors, the judgment of ...
