摘　　要：研究建筑工人夏季热反应对保障建筑工人生命安全、减少安全事故的发生具有重要意义.通过施工现场实地调研,借助TAITherm软件,建立虚拟人体模型,还原建筑工人户外工作时生理参数变化,利用相关性分析、建立回归模型等数学手段,研究建筑工人生理参数和热环境参数之间的关系.结果表明:核心温度模拟值和实测值接近,平均皮肤温度模拟值与实测值走势相似;平均皮肤温度、平均皮肤温度变化率会对环境变化快速响应,核心温度响应时间滞后约3 min;短暂的休息可以有效降低平均皮肤温度、心输出量,但对降低核心温度作用不显著;活动时长是影响生理参数的重要因素,且随活动时长增加人体调节机制变弱.It is of great significance to study the thermal response of construction workers in summer to ensure their personal safety and reduce the occurrence of safety accidents. Through field investigation at construction sites and with the aid of TAITherm software, a virtual human body model was established to restore the changes in the physiological parameters of construction workers at outdoor work. Mathematical means such as correlation analysis and regression models were used to study the relationship between the physiological parameters of construction workers and thermal environment parameters. The results show that the simulated core temperature is close to the measured value, the trend of the simulated average skin temperature is similar to the measured value,the time lag of core temperature response is about 3 min. Short rests can effectively reduce the average skin temperature and cardiac output, but has no significant effect on core temperature reduction. Activity duration is an important factor affecting physiological parameters, and the regulation mechanism of the human body becomes weaker with the increase of activity duration.
