Abstract

The invention provides an urban subway inland inundation disaster toughness evaluation method. The method comprises the following specific steps: S10, constructing an urban toughness restoring force evaluation model by using a function of disaster intensity and an urban system functional change rate; s20, on the basis of the urban toughness restoring force evaluation model, an urban subway waterlogging disaster toughness index system is established and comprises first-level indexes and second-level indexes, the first-level indexes comprise the structure, the performance and the business, and each first-level index corresponds to a plurality of second-level indexes; s30, determining a first-level index weight by using an analytic hierarchy process; s40, determining a second-level index weight by using a grey relational analysis method; and S50, calculating the city toughness by using the weight of each level of index.

Description

technical field [0001] The invention relates to the technical field of urban waterlogging disaster assessment, in particular to a method for evaluating urban subway waterlogging disaster resilience. Background technique [0002] With the increase of extreme weather in recent years, the problem of urban waterlogging is becoming more and more serious. Waterlogging not only submerges roads, but also brings great challenges to urban infrastructure, such as flooding of high-pressure natural gas stations, subsidence of roads and crushing of underground pipelines, backflow of subways, etc. . [0003] In order to provide basic guarantees for the normal operation of the city and the normal production and life of citizens, and to improve the capital’s risk management capabilities and emergency support levels, it is necessary to conduct risk assessments for urban waterlogging caused by heavy rains, so as to carry out targeted prevention and treatment, which is the key to reducing urban...
