通过分析青藏铁路错那湖段气候特征、地质地貌、植被、沙丘分布及特征的基础上,分析了该地段铁路沙害的类型与成因,并对近年来在青藏铁路错那湖段采用的固沙和阻沙工程防沙措施进行了评价。从工程性价比、风沙流成因和防护效果的综合角度出发,提出了采用尼龙网沙障、混凝土沙障、活动板挡沙栅栏、截沙沟等阻沙措施和卵(碎)石覆盖沙面、覆膜沙袋沙障等固沙措施以及植物措施相结合防沙措施的建议,这种防沙体系的结构配置对该地段铁路沙害防治具有重要的指导意义,对青藏高原其他地区的铁路、公路防沙也有一定的借鉴意义。
Based on the analysis of the climatic characteristics, geomorphology, vegetation and dune distribution and characteristics of the fault section of the fault section of the Qinghai-Tibet Railway, the types and causes of the railway sand damage in this section are analyzed. In the recent years, And sand control project sand control measures were evaluated. From the perspective of engineering cost performance, the causes of sand flow and the protective effect, this paper proposed the use of nylon net sand barrier, concrete sand barrier, movable plate retaining sand fence, sand cutoff and other sand-blocking measures and egg (broken stone) The sand-barrier with sandbag and other sand-fixing measures as well as the combination of plant measures to prevent sand. The structural arrangement of the sand-control system has an important guiding significance for the prevention and control of railway sand hazards in this area. Sand also has some reference.
