Research On Metro Project Quality Supervision Based On Blockchain

In recent years,with the continuous expansion of the scale and number of subways in China,more and more people have paid attention to the quality of subway projects.The subway project has many difficulties,such as complex external environment,complex technology,and great difficulty in project coordination.In view of these difficulties,the practitioners groped ahead in the project supervision scheme.With the development of digital technology in China,blockchain technology has gradually matured and been applied to the construction industry,triggering a new round of technological revolution in the construction industry.The advantages of blockchain technology information sharing in a timely manner,information openness and transparency,and traceability to the source of quality can effectively solve the technical pain points of subway construction.Nowadays,the research on the application of blockchain technology in the construction industry only focuses on the platform concept of blockchain technology,and lacks specific supervision schemes for subway projects.In view of this research gap,this thesis takes the construction in progress of Shenyang Metro Line 6 as an example to build a subway project quality supervision framework based on blockchain technology.The evolutionary game model is used to analyze the regulatory decision-making choices of the government and enterprises,and Matlab2016 b software is used to conduct numerical simulation to verify the model,find out the factors that affect the regulatory decision-making choices of Shenyang Metro,and build a project supervision model based on blockchain technology based on the decision-making factors.Find out the factors that affect the supervision of subway projects through literature query and expert consultation,analyze the influence degree of each factor through structural equation model,and propose the supervision process based on blockchain technology according to the key factors that affect the supervision of subway projects combined with blockchain technology.This study establishes a blockchain supervision engineering quality system taking Shenyang Metro Line 6 as an example,and systematically studies the blockchain supervision engineering mode and process,which provides scientific theoretical guidance for the application of blockchain technology to subway engineering quality supervision.Blockchain technology provides a new quality management idea for governments and construction enterprises,and accelerates the informatization process of the construction industry.
