Urban typical bridge quick demolition scheme decision-making software system

Abstract

The invention provides a decision-making software system for a quick demolition scheme of an urban typical bridge. The decision-making software system is characterized by comprising an evaluation model establishment module, a data collection module and a scheme optimization module, wherein the evaluation model establishing module is used for setting a scheme database, an index system and corresponding index weights; the data collection module is used for receiving the parameters of the bridge to be dismantled and quantifying the input parameters according to the index system and the corresponding index weights; and the scheme optimization module brings the quantified parameters into alternative schemes in a scheme database, performs single-method decision making on the alternative schemesthrough multiple multi-criterion decision making methods, performs unified processing on multiple decision making results, completes comprehensive decision sorting and outputs an optimal quick dismantling scheme. According to the method, the demolition efficiency is improved, the decision risk and the construction risk are reduced, and a decision maker is assisted to improve the decision efficiency and select a reasonable quick demolition scheme.

Description

technical field [0001] The invention relates to the technical field of bridge engineering in the transportation industry, in particular to a decision-making software system for rapid demolition schemes of typical urban bridges. Background technique [0002] With the accelerated development of urbanization in my country, the structural resistance of bridges declines rapidly due to factors such as congenital design and construction quality defects, changes in use functions, road network re-planning, environmental erosion and vehicle overloading during operation, and the safety and security of many bridges. Reliability and traffic capacity are difficult to meet the growing traffic demand, and the demand for demolition is increasing. However, typical urban bridges are located in densely populated areas and have a large traffic flow. Conventional bridge demolition schemes cannot meet the needs of rapid and safe demolition and smooth traffic at the same time, which brings great cha...
