摘  要:为评估超高海拔隧道施工人员劳动强度,采用理论分析法确定施工人员劳动强度评价指标,并依托某超高海拔隧道采用可穿戴设备监测分析不同工序施工过程中人员生理指标变化,进而计算不同工序人员劳动强度及劳动效率。研究结果表明:不同工序施工人员劳动过程中生理指标变化存在明显区别,其中,二衬钢筋布设人员心血管负荷超过卫生限值,机械操作人员血氧饱和度(SpO 2)低于规范值;超高海拔隧道二衬钢筋布设劳动强度为Ⅴ级,底板施工与仰拱钢筋绑扎劳动强度等级为Ⅲ级,二衬防水布铺设与机械操作人员劳动强度等级为Ⅱ级;海拔4700 m时,隧道施工人员劳动效率仅为平原地区的76%~88%;完成与平原地区相同的工作量,相应工序的人工工日消耗需要增加13.63%~31.58%。To assess the labor intensity of construction personnel in ultra-high-altitude tunnels,this study employed theoretical analysis to define evaluation indicators and used wearable devices to monitor physiological changes during various construction phases in a specific ultra-high-altitude tunnel.Subsequently,labor intensity and efficiency of different tasks were calculated.Results reveal that the physiological indicators of different tasks are significantly different.Specifically,cardiovascular loads of the workers installing secondary lining steel bars exceed the hygienic limits,and peripheral oxygen saturation(SpO 2)levels of the mechanical operators is lower than the standard values.Labor intensity is classified as Grade V for installing secondary lining steel bars,Grade III for bottom plate construction and arch steel bar binding,and Grade II for installing secondary lining waterproof cloth and for mechanical operations.At an altitude of 4700 meters,the labor efficiency ranges only from 76%to 88%compared to the plain areas.To match the workload in the plain areas,the labor input must be increased by approximately 13.63%to 31.58%depending on the process.
