Study On The Evaluation Of Highway Construction Projects Design Quality

Quality is a hot topic of the research areas.product design is the soul of the product quality,product design work on the final quality of the product has a profound impact. The roadconstruction project survey and design work which can be divided into different levels ofcomplex systems composed of many factors, establish and improve China’s road constructionproject design evaluation system, the administrative departments at all levels as well as theoryand practitioners are facing an important task. In this regard, the relevant administrativedepartments also established a credit rating system of survey and design units, but theevaluation system is not perfect, the need to create a complete set of design quality evaluationsystem so as to form an effective engineering construction design management system,management and supervision department on the highway The design quality of theconstruction project objective to evaluate.In this paper, the analysis of the design quality evaluation method of construction projectsat home and abroad, combining characteristics of road projects, highway construction projectdesign quality evaluation program, the comparative analysis of the evaluation of the programelements of the evaluation, select the design suitable for highway construction projects qualityevaluation of programs; using the analytic hierarchy process and expert scoring method todetermine the weights of an index; an indicator of the quality of the overall project design,through engineering examples, data analysis and research of experts to determine the weightsof the five secondary targets and indicators; subgrade, pavement, bridges and culverts, tunnel,cross the engineering and traffic engineering design six-level indicators are used changes inthe number of program changes and major projects to evaluate the two secondary indicators,taking into account the impact of the two secondary indicators of the quality of design ofvarious highway projects in varying degrees, in order to ensure that evaluation resultsobjectively fair, the program changes and the main project the number of changes to the set ofthe same weight; to determine the various evaluation factors of engineering changes to theproject, and project the number of changes to the content rating standards and rating methods,the establishment of a based on fuzzy comprehensive The evaluation method of project designquality evaluation model to determine the design quality level of the highway constructionproject, alone in the evaluation process is to reduce thesubjective and one-sidedness of theexpert evaluation, impartiality and objectivity of the evaluation results.
