【摘要】：為了找出高溫高濕作業(yè)環(huán)境下人員勞動強(qiáng)度對生理、心理指標(biāo)的影響規(guī)律,在實(shí)驗室建立了高溫高濕環(huán)境模擬體系。試驗人員選擇年齡相近、身體狀況相仿的50名在校大學(xué)生,設(shè)定了微風(fēng)(風(fēng)速小于1.5 m/s)及濕球黑球溫度(WBGT)為26℃、33℃、35℃、38℃以上4種環(huán)境條件,試驗人員按事先規(guī)定的運(yùn)動方式從事極重體力勞動和重體力勞動負(fù)荷訓(xùn)練,實(shí)時監(jiān)測人員心率和評價主觀疲勞程度,計算人員心血管負(fù)荷(CVL)和主觀疲勞程度,對數(shù)據(jù)進(jìn)行相關(guān)性分析,并繪制不同勞動負(fù)荷、不同環(huán)境溫度下的柱狀趨勢圖。結(jié)果表明,在同等勞動負(fù)荷下,人員心血管負(fù)荷和主觀疲勞程度與環(huán)境溫度(WBGT)存在正相關(guān)性。根據(jù)人員心血管負(fù)荷預(yù)警級別,提出當(dāng)作業(yè)環(huán)境溫度(WBGT)達(dá)到35℃及以上時,應(yīng)立即停止人員重體力和極重體力勞動負(fù)荷作業(yè)。根據(jù)試驗結(jié)果,結(jié)合現(xiàn)場實(shí)際,提出從事高溫高濕作業(yè)的人員,應(yīng)合理安排勞動和作息,加強(qiáng)水鹽及營養(yǎng)的補(bǔ)充,加強(qiáng)個體健康監(jiān)護(hù)。
[Abstract]:In order to find out the influence of labor intensity on physiological and psychological indexes in high temperature and high humidity working environment, a simulation system of high temperature and high humidity environment was established in the laboratory. The participants selected 50 college students of similar age and physical condition, and set up four environmental conditions such as breeze (wind speed less than 1.5m / s) and wet bulb black ball temperature (WBGT) of 26 鈩，
