Application Of BP Neural Network In Layout Optimization Of Construction Site

Now with the continuous development of science and technology and economy,has greatly promoted the development of social progress,whether it is the construction,project acceptance and post operational stages,or project safety,quality,schedule and cost,construction site layout has a profound impact on the project,the construction site layout is reasonable,the optimal the allocation of resources,improve the efficiency of construction project,which achieved the goal of the project.Therefore,whether the layout of the construction site is reasonable is a long-term problem and needs to be constantly improved.In recent years,along with the healthy development of China's construction industry and the steady improvement of safety construction,the level of construction safety management has been significantly improved,but there is still a significant gap compared with the western developed countries.In this paper,the highway project as an example,starting from the construction site layout,the BP neural network theory and methods applied to the construction site layout work to establish the management system of construction site layout,the layout of real time control of the construction site,safety evaluation of construction site layout in real time.This paper first summarizes the research status of the construction site layout at home and abroad,introduces the related safety management theory,summarizes and analyzes the traditional optimization methods of the layout of the construction site,and compares their respective advantages and disadvantages.At the same time,it puts forward the conception of the safety management system of the highway construction plane layout.Secondly,it introduces the mathematical algorithm process and basic principles of BP neural network,analyzes its advantages and disadvantages,and puts forward the corresponding improvement methods.Based on the improved BP neural network algorithm,it establishes the mathematical foundation of the safety management system for the layout of construction site.Then the MATLAB software is used to compile the neural network model program for the layout of the construction site,and the appropriateparameters and network structure are selected.According to the 10 evaluation attribute,collect the security experts on the construction site of the security situation inspection score of training the neural network and its application to the engineering example,the BP neural network model to evaluate layout construction,thus the BP neural network in the construction site layout in the management system,play a role.
