论述了玉溪-普洱输气管道工程项目概况,并对线路走向三个方案进行了全面分析。其中南线方案走向为:管道始于峨山县双江镇白泥村,终于终点峨山末站,线路全长约25.53 km,本段线路沿线地形地貌主要为山间沟谷及丘陵,沟谷内主要为岩质山体,出落岩体清晰可见,岩石强度较大。地表状况主要为旱地、农田及林地。中线方案:管道始于峨山县双江镇白泥村,线路长约22.43 km。本段线路沿线地形地貌主要为山间沟谷及丘陵,地表状况主要为农田、旱地和林地。北线方案:本段线路长约24.61 km,线路沿线地貌主要为山间沟谷及丘陵,地表状况主要为农田、旱地和林地等。对三个方案的工程量及优缺点进行了分析计算并结合规划情况,得出中线方案穿越工程较少,总投资少,线路走向应采用中线方案。
The general situation of Yuxi - Pu’er gas pipeline project is discussed, and a comprehensive analysis of the three schemes is made. Among them, the southern line will be headed by: the pipeline started from Baisha Village, Shuangjiang Town, Eshan County, and finally ends at Eshan Terminal Station. The total length of the line is about 25.53 km. The topography of the main line along the route is mainly mountain valleys and hills. Rocky mountains, rock mass clearly visible, rock strength greater. Surface conditions are mainly dry land, farmland and woodland. Midline program: The pipeline starts in Pak Nai Village, Shuangjiang Town, Eshan County, with a length of about 22.43 km. The topography of the main routes along the route is mountain valleys and hills. The surface conditions are mainly farmland, dry land and woodland. North Line Program: This section of line length of about 24.61 km, along the line is mainly mountainous valleys and hills, surface conditions are mainly farmland, dry land and woodland. Based on the analysis and calculation of the project quantity, advantages and disadvantages of the three schemes and the planning situation, it is concluded that the midline scheme has fewer traversing projects, less total investment and the line direction should adopt the midline scheme.
