Embodiment 1

[0038] Embodiment 1 Construction of comprehensive evaluation index system for bridge intelligence

[0039] The basic principle of constructing the comprehensive evaluation index system of bridge wisdom is that the index selection should be scientific and operable. The principle of scientificity is to reduce subjectivity as much as possible in the process of constructing the comprehensive evaluation index system of bridge intelligence. The selected indicators should be representative, pertinent and comparable. The characteristics and characteristics of intelligent bridges. The operability principle means that the index data acquisition and quantification of the selected bridge intelligence evaluation index system should be simple, clear and easy to calculate, so that the evaluation index system can be promoted and applied.

Embodiment 2

[0044] Example 2 Using the Analytic Hierarchy Process (AHP) to calculate index weights

[0045] The following takes the index weight calculation process of the daily operation and management of smart bridges as an example to illustrate the value assignment process of the analytic hierarchy process.

[0046] 1. According to the research purpose, establish the hierarchical structure of the daily operation and management of smart bridges in service (Table 2).

[0078] Embodiment 3 Obtaining the comprehensive value of bridge intelligence evaluation and determining the comprehensive evaluation grade standard

[0079] 1. Obtain the comprehensive value of bridge intelligence evaluation

[0080] Combining the final combined weight of each indicator with the measured value of each indicator and then summing it is the value of the comprehensive evaluation of bridge wisdom. The formula for calculating the comprehensive value of bridge intelligence evaluation is as follows:

[0081] S = Σ i = 1 n W i · P i ( v ) , ( i = 1 , 2 , 3 , ...

Abstract

The invention discloses a bridge intelligent degree comprehensive evaluation index selection and quantification method. The method particularly comprises the steps that bridge intelligent degree comprehensive evaluation indexes are selected; quantification reference bases are made according to the bridge intelligent degree comprehensive evaluation indexes; a measured value P of a bridge intelligent degree base index is calculated according to all the quantification reference bases of all the indexes; weights W of all stages of the indexes of a bridge intelligent degree evaluation system are obtained through an analytical hierarchy method; a bridge intelligent degree evaluation comprehensive value S is obtained, and the grade of bridge intelligent degree comprehensive evaluation is established. According to the bridge intelligent degree comprehensive evaluation index selection and quantification method, the characteristics of the bridge intelligent degree are reflected from different aspects, and representativeness, pertinence and comparability are achieved; obtaining and quantification of index data are simple and clear and easy to calculate; the degree of relative intelligence of a bridge is converted into a value within an interval and becomes an objective scale for measuring the bridge intelligence efficiency, and practicability and effectiveness are achieved.

Description

technical field [0001] The invention relates to the field of comprehensive assessment of building conditions, in particular to a method for selecting and quantifying indicators for comprehensive assessment of bridge wisdom. Background technique [0002] With the wave of smart cities sweeping the world, the demand for smart bridges, an indispensable part of smart cities in the construction of transportation infrastructure, is increasing. At this stage, in order to provide scientific and technological support to ensure the safety of bridges, my country has not only achieved a number of independent innovation achievements in bridge design, construction, monitoring and maintenance, but also in bridge construction technology, new structures and high-performance materials, management and maintenance technology, and informatization. Technology and other core technologies and equipment technological innovations are also gradually narrowing the gap with the international level. Throug...
