When attacked by weapons of mass destruction, underground engineering will operate under isolation condition, which results in the increase of temperature, humidity, and CO₂ concentration. At present, there are few studies on personnel thermal comfort and working efficiency in underground engineering, especially under isolation condition. To improve the personnel thermal comfort and working efficiency under such condition, the influence of environmental temperature changes on human thermal comfort and working efficiency was investigated through a combination of subjective and objective methods. A subjective questionnaire and working efficiency test were conducted on the subjects in the artificial climate chamber, and synchronously monitored electrocardiography (ECG), electroencephalography (EEG), and other physiological parameters of the subjects were recorded, when isolation condition was achieved in the artificial climate chamber. The results show that: (1) the human neutral temperature is 24.2 °C, and thermal comfort zone is [23 °C, 25.5 °C] for isolation condition; (2) the high working efficiency area is [27.3 °C, 28.8 °C] for isolation condition; (3) the average of the TSV corresponding to the highest working efficiency point is 1.3 under isolation condition; (4) from the correlation analysis of working efficiency and personnel physiological indicators, personnel EEG index and task performance are significantly related, and the ECG index and task performance are not relevant for subjects performing brain work under isolation conditions.

当受到大规模杀伤性武器攻击时，地下工程将在隔离状态下运行，导致温度、湿度和CO _2升高专注。目前，关于地下工程特别是隔离条件下人员热舒适性和工作效率的研究较少。为提高人员在该条件下的热舒适度和工作效率，采用主客观相结合的方法，研究了环境温度变化对人体热舒适度和工作效率的影响。在人工气候舱内对被试进行主观问卷调查和工作效率测试，在人工气候室内达到隔离条件时，同步监测被试的心电图（ECG）、脑电图（EEG）等生理参数。室。结果表明：（1）人体中性温度为24.2℃，隔离条件下热舒适区为[23°C，25.5°C]；(2) 高工作效率区为[27.3°C, 28.8°C] 隔离条件；(3)隔离条件下最高工作效率点对应的TSV平均值为1.3；(4)从工作效率与人员生理指标的相关性分析可知，人员脑电指标与任务绩效显着相关，而孤立条件下进行脑部工作的受试者心电指标与任务绩效不相关。
