Decision-making method for rapid demolition scheme of urban typical bridge

Abstract

The invention provides a decision-making method for a rapid demolition scheme of an urban typical bridge. The decision-making method is characterized by comprising the following steps: a, acquiring related index parameters of a to-be-demolished bridge; b, obtaining a selectable dismantling scheme; c, calculating the resistance scores of all the demolition schemes based on the related index parameters of the to-be-demolished bridge, and selecting a plurality of demolition schemes with weaker resistance as an alternative scheme set; d, performing single-method decision making on all the alternative schemes through multiple multi-criterion decision making methods; and e, performing unified processing on a plurality of decision results and finishing comprehensive decision sorting, wherein thedecision result with the highest sorting is the optimal quick dismantling scheme. Aiming at the defects in the prior art, the invention provides the decision-making method for the rapid removal schemeof the urban typical bridge, and the most suitable bridge removal method is effectively selected.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a decision-making method for a quick demolition scheme of a typical urban bridge. 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 challenges to the demolition project. I...

[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. The 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 with heavy traffic flow. Conventional bridge demolition solutions cannot meet the needs of rapid and safe demolition and smooth traffic at the same time, which brings great challenges to the demolition project.

In the existing technology, the demolition project involves many procedures, complex processes, and difficult construction, which is prone to accidents, resulting in painful casualties and huge economic losses. The demolition plan is highly subjective
