Abstract

The invention provides a method and device for evaluating the function toughness for road traffic after an earthquake, and relates to the technical field of toughness evaluation. The method comprisesthe steps: determining a target transportation network to be evaluated, and acquiring a seismic damage situation of the target transportation network; segmenting the target transportation network to obtain multiple road segments; obtaining the area of each road segment and the recovery time after the earthquake; calculating the recoverability weight coefficient of each road segment according to the recovery time after the earthquake; calculating a functional toughness index of the target transportation network according to the area and recoverability weight coefficient of each road segment. According to the method and device, the target transportation network is divided into the road segments, and the area of each road segment and the recovery time after the earthquake are obtained. The method and device can calculate the recoverability weight coefficients to obtain the functional toughness index of the target transportation network, and an objective evaluation method for the post-earthquake functional toughness of road traffic is provided.

Description

technical field [0001] The invention relates to the technical field of toughness evaluation, in particular to a method and device for evaluating road traffic post-earthquake functional toughness. Background technique [0002] Earthquake resilience is to evaluate the recovery ability of roads in a region after an earthquake from the perspective of earthquake resilience. In this regard, due to previous ignorance and little data accumulation, little is known about the functional resilience of road traffic after earthquakes, and there are even fewer related studies. At present, there is no objective evaluation method for the post-earthquake functional resilience of road traffic. [0003] For the above-mentioned problem in the prior art that there is no objective evaluation method for the post-earthquake functional resilience of road traffic, no effective solution has been proposed yet. Contents of the invention [0004] In view of this, the object of the present invention is...
