Research And Practice On Construction Quality Management Of H Expressway Project

In recent years,with the rapid development of China’s society and steady improvement of the economic level,the process of urbanization is further accelerated,and the scale of infrastructure investment continues to expand.In order to meet the needs of the urban population in terms of living convenience and travel convenience,more and more urban expressway construction is presented in our vision.With the increase of construction quantity,quality accidents related to expressways occur from time to time,which not only bring great harm to people’s lives and property,but also have a bad impact on the construction industry.Therefore,the construction quality management level of urban expressways needs to be improved urgently.Taking H expressway project as an example,this paper discusses how to strengthen the quality management of expressway construction,and puts forward relevant countermeasures and Suggestions.First of all,combined with H expressway project(hereinafter referred to as the "H" engineering)characteristics of the project,project planning,quality system engineering project quality policy and objectives,and through the establishment of quality management organization and personnel quality responsibility,from four aspects: thought,organization,technology and system to build quality assurance system in order to guide the construction.Secondly,the WBS theory is introduced,and the construction process decomposition method is adopted to decompose the H project layer by layer to determine the construction content.The construction process is presented by means of tree diagram,which provides a theoretical basis for the identification of the following construction quality key processes.Again,using the method of mathematical statistics collected in the process of construction quality problems in order,and use the WBS decomposition results,classifies the problem of collecting and using the pareto chart method to identify the problems exist in the construction of more prominent key working procedure,through consulting a large number of literature and special conference research carried out on the key processes of the quality problem,in-depth H engineering construction quality factors,identify H engineering construction quality factors influencing causal analysis diagram,for the subsequent construction quality control measures are put forward to provide guidance.Finally,in order to guarantee H to effectively control the engineering construction quality,targeted put forward some countermeasures and Suggestions,mainly including: in the light of the construction of key process and the quality influencefactors respectively formulate the corresponding control measures,from four aspects:thought,organization,technology and system to improve the implementation of quality assurance measures for enhancing optimization of construction quality control measures,introducing PDCA cycle to achieve the H engineering construction quality control of continuous improvement Suggestions,in order to ensure engineering quality of H,achieve the ultimate goal of management work,in order to ensure quality control of present and subsequent construction.In this paper,by making use of theories and methods of project quality management related to research how to improve the quality of H project management level,to promote the application of the theory of quality management in expressway engineering and practice,this paper established the quality management system,identify the key process and influencing factors of quality and put forward relevant countermeasures and Suggestions,to late H engineering and offer reference for similar projects.There are 13 figures,20 tables and 84 referrnces in this paper.
