Quality Control Research Of Subgrade Construction Project Of High Speed Railway

With the development of China's economy and the improvement of people's living standards,more and more travel choices have been made.High-speed railway has become the first choice for people to travel because of its comfortable ride and fast speed.As the foundation of high-speed railway operation,the stability of roadbed has become the top priority of our attention.Therefore,careful analysis and Research on the quality management of high-speed railway subgrade is of great significance.Through a lot of literature research and analysis,this paper puts forward the current situation of project quality control development in China:low efficiency of project quality control;Quality control methods stagnate;Overall quality control development slow.At the same time,the paper summarizes the quality problems of China's high-speed railway subgrade engineering,and analyzes the main reasons of which are the neglect of project quality control,and few systematic application of project quality control methods.In view of the above problems,this paper takes the subgrade engineering quality control of the third bidding section of high-speed railway as the research object,and combines the practice of subgrade engineering construction in this section,discusses the ideas and methods to solve the subgrade engineering quality control problems of high-speed railway.Firstly,it defines the basic concepts of highway subgrade engineering and project quality control,studies the connotation of total quality control and its PDCA cycle program,and then puts forward the idea of applying AHP to construction quality control of high-speed railway subgrade engineering.Secondly,the impact of the quality of the project,the impact of the analysis of the quality of the high-speed rail project,and the key factor of the question,and based on the analysis of the quality of the high-speed railway,is based on the idea of the quality control model of the high speed rail road,which will be a quantitative and qualitative analysis,and it will affect the quality control in the construction of the high-speed railway engineering,and it will be a tool that the engineering managers and the experts are going to do,and the key to the quality control will be controlled in advance,and it will be controlled by the quality control;Finally,according to the PDCA cycle program of comprehensive quality control for the subgrade project of high-speed railway,the quality control model for the construction of the high railway subgrade project is preliminarily verified and applied.The effect of project quality control is summarized.From the implementation of the project,the control of the construction quality of the case project is relatively successful.The project pays attention to the use of advanced quality management concepts and tools to implement the construction process,the implementation of the "PDCA" cycle of quality control methods,quality control concerns throughout the project.Only need to strengthen the implementation of the management process,strengthen the management of people,through continuous improvement and strengthening,I believe that the project quality management measures will achieve better results.
