This is based on the evaluation of the management quality theory, by integrating the related theory; we present a comprehensive Six Sigma quality management theory for highway engineering quality supervision and management. This theory uses the total quality management theory to realize the full responsibility of the main participation, and it uses Six Sigma quality management theory to guide the various stages and key processes of quality management, and it uses fuzzy comprehensive evaluation method to achieve the evaluation of the entire project and the various processes. This essay provides the working program which uses this theory and the corresponding quality management content.
In this paper, the combination of antenna array detection method of ground penetrating radar is put forward to solve the actual engineering problem that it is difficult to monitor the length of CFG pile. The experiments of length of six CFG piles find that the relative error of the length is 5.26%. The result indicates that it is enough reliable to determine the pile length by using the GPR method and can meet the engineering needs. Furthermore, the effect of the mix proportion, moisture content on the monitoring quality is obtained.
The scientific aspects of hydrogen storage in a single Mg atom have been investigated by density functional theory (DFT) calculations on gas-phase MgHn (n=1-20) clusters. It was found, at least...
Because it is difficult to monitor the quality of gravel pile (the length, the diameter) in composite foundation, the method of radar is put forward. Numerical simulations of radar monitoring on flexural pile are processed. The results show that the method of radar monitoring can be used to check the quality of gravel piles (length, diameter) accurately. Then this technology is applied in some highway project. By comparing with the results of another company, the characteristics including high precision and speed are found. So the technology can be far and wide used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
