1解读极旱荒漠地区在铁路路基施工中的节水方案Interpret the extremely drought desert region in construction of the railway roadbed water saving scheme 极旱荒漠区域，水资源极度缺乏，在铁路路基施工中，对现有水资源进行科学合理计划、运用，保证路基填料到达最佳含水率，满意路基施工标准需求，为极旱荒漠区域进行铁路路基施工供给可学习的施工经历。 1 工程概略 中铁十七局集团承建的兰新铁路第二双线 17 标地处甘肃省酒泉市瓜州县柳园镇镇极旱荒漠区域，线路途经区域为戈壁、荒滩，气候枯燥，降水少，蒸腾量大，地下水资源缺乏。该区域年均气温 8.8℃，均匀日较差16.1℃，年较差 35.3℃，极点最高气温 42.8℃，极点最低气温 -29.1℃；年均降水量45.7mm，年蒸腾量 3140.6mm，年相对湿度 39-41％，无霜期 138-146 天；10m 高度年均匀风速 6.2m/s，40m 高度年均匀风速 7.57m/s。线路正线长 104.679km。其间路基工程99.789km（含站场），地基处置描绘 86.32km，区间路基土石方 1339.05 万 m3；站场路基土石方 54.79 万 m3。 2 施工过程中的节水计划 Extremely dry desert area, water resources shortage, during the construction of railway subgrade, to scientific and reasonable planning, use of the existing water resources, guarantee the roadbed fillers reach the optimum moisture content, satisfied with subgrade construction standard requirements, for the extremely arid desert area of railway roadbed construction supply can learning experience. 1 an railway engineering general China railway 17th bureau group constructed by 17 second double standard is located in jiuquan city, gansu province, the melon counties LiuYuan ZhenZhen extremely dry desert area, line via area as the gobi, wasteland, dry climate, less precipitation, transpiration is big, the lack of water resources. The regional annual average temperature 8.8 , the diurnal range 16.1 , lower 35.3 , extreme maximum℃℃℃ temperature 42.8 , extreme minimum temperature of 29.1 ; Average annual rainfall of 45.7℃...
