Comprehensive comfort assessment method for the weight of environmental factors by analogical reasoning: A study on the comfort of the tunnel construction environment

Abstract

During the tunneling process, the numerous and dense electromechanical equipment and shield machine facilities will release a significant amount of heat and noise, and emit various harmful gases and dust, severely influencing the comfort of the construction environment. In this case, it is highly necessary to study the comfort of the tunnel construction environment. This paper presents a comprehensive assessment method for the comfort of the construction environment in the tunnel by analogical reasoning based on standard specifications and known similar situations. The index formula and evaluation grade of four environmental factors in the tunnel construction environment were first proposed according to relevant standard specifications at home and abroad, and the new entropy grey correlation analysis (EGCA) weighting method is used to calculate the objective weight scheme by analogical reasoning. Then, 486 valid questionnaires were collected by network questionnaire, and the subjective weight scheme was obtained through expert evaluation in the fuzzy analytic hierarchy process (FAHP). The combined weight scheme was finally obtained based on the results of game theory combining the EGCA and FAHP methods. The rationality and correctness of the method are verified by data. Furthermore, this study compared the weight schemes of other studies, and the results show that tunnel construction workers have higher requirements for thermal and air environments than workers in public buildings. This method can help designers and users estimate and evaluate comfort through standard specifications and known similar situations on occasions where actual data are difficult to obtain. With the improvement of data, the research results can be gradually adjusted and optimized.
