公路工程材料試驗檢測影響因素的研究
[Abstract]:In the construction of highway engineering in China, test and inspection is an important part of highway engineering construction and maintenance management, and it is an indispensable part of quality control and acceptance evaluation of completion. In recent years, in engineering construction due to the quality of structures that do not meet the standard and lead to scrap, the causes of quality accidents are various, but many engineering quality problems can be seen in the trace of material problems. It is difficult to control the working quality completely because there are many influencing factors in the test. In this paper, based on the background of highway engineering test and test, taking engineering materials as the analysis object, through analyzing the factors and the degree of influence on the test and test quality in the course of highway engineering material test and testing, the appropriate management scheme is put forward. It is of practical significance to improve the test level. In this paper, the current situation of material test and inspection management is analyzed, the work mode and concept of highway engineering test and inspection are defined, the contents of engineering material are introduced briefly, and the management system and test 4M1E (human being) are introduced. Machine, material, method, ring are analyzed. Through literature review, expert analysis and investigation with enterprise examiners, the possible influencing factors in the process of testing and testing are obtained, and the influencing factors determined in these three aspects are analyzed synthetically. Finally, the index of influencing factors was determined. Then, the influence factors of material test are analyzed by AHP, and the relative importance weight of the index is obtained. Through the comparison of the weight of importance, the influence degree of each influencing factor on the quality control of test detection is determined, and the control scheme that should be adopted in the process of test and test is obtained. Finally, according to the case analysis of the enterprise, the cement test project is introduced to study the influencing factors, and the test and detection of the specific project parameters should be controlled according to the characteristics of the parameters and on the basis of overall management. In this paper, based on the practical experience of engineering material test and testing, according to the present management situation and methods, the influencing factors of material test and testing are deeply studied. The research results can promote the improvement of the quality of testing and testing.
