| 中文摘要 | 青藏铁路西宁至格尔木段(西格段)日照冻融变化强烈、风力强劲,为了解决该环境下戈壁风沙流对路基的危害,以PE(polythene)固沙网为平面防治并结合高立式沙障为立面防治措施,组成了戈壁风沙流防治体系,通过现场观测及室内风洞实验,验证了该防治体系的防风固沙效果和工程可靠性。工程应用表明,该防治体系具有抗风蚀性能强、可重复利用、寿命长及绿色环保等特点,能够有效防治铁路戈壁风沙流的危害,并对养护工作量的减少起到了重要作用,可以替代传统石方格、竹栅栏等防风固沙措施。对类似于西格段这种戈壁风沙流速较大、海拔高、生态脆弱、传统防沙材料贫乏和工程防沙措施失效的地区,新型防治体系具有借鉴和示范作用。 |
| 英文摘要 | In order to prevent the wind-blown sand damage on subgrade engineering in Xining-Golmud section of Qinghai-Tibet Railway in the plateau gobi environment with strong sunshine,severe freezing and thawing and powerful wind,we took PE (polythene)sand-fixation nets and high vertical wind resistance fences as plane measure and vertical measure respectively to make up a new gobi wind-blown sand prevention system.Field observation and indoor wind tunnel experiment proved its wind-blown sand preventing effect and reliability.Engineering application indicated that the new wind-blown sand prevention system possessed advantages of wind erosion resistance,reusability,long-life and environment protection,and at the same time it reduced daily maintenance workload.So the wind-blown sand prevention system could effectively prevent the gobi wind-blown sand damage on the railway,and could eventually replace the traditional sand-fixing measures of stone checkerboards,bamboo fence and etc.Under the similar circumstance with characteristics of much gobi wind-blown sand,high altitude,fragile ecological environment and scarcity of traditional wind-blown sand prevention materials,the new prevention system might be much suitable. |
