摘要
探究建筑工人作业疲劳与各项指标之间的关系对于建筑单位疲劳预警研究、安全事故预防具有重意义。运用主客观结合的方法,通过测试和采集30名一线建筑工人班前和班后的主观疲劳水平、平均反应时和时间知觉误差等指标并进行分析,以确定疲劳水平与各指标之间的关系。结果表明:被试工人班前班后的各主客观指标的配对数据T检验均呈现显著性差异,疲劳水平与生理疲劳度、心理疲劳度、平均反应时呈现较强的正相关关系。工人班后均出现不同程度的疲劳现象;平均反应时可作为评价建筑工人疲劳有效的客观生理指标。
Exploring the relationship between the operational fatigue of construction workers and various indicators is of great significance for the study of early warning of fatigue and safety accident prevention in construction units.Using a combination of subjective and objective methods,this paper tests,collects,and analyzes the subjective fatigue level,mean reaction time,and time perception error of 30 front-line construction workers before and after shifts,so as to investigate the relationship between fatigue level and each index.The results show that the paired data t-tests of the subjective and objective indicators of the workers before and after shifts show significant differences,and the fatigue level shows a strong positive correlation with the physiological fatigue level,the psychological fatigue level,and the average reaction time.The workers all show different degrees of fatigue after shifts;the average reaction time can be used as an objective physiological indicator to evaluate the fatigue of construction workers effectively.
