综合选线技术在宝麟铁路勘察设计中的应用

Application of Integrated Route Selection Technology in Survey and Deign of Bao-Lin Railway

通过对麟游矿区至宝鸡二电厂铁路线(简称宝麟铁路)在穿越不良地质区、采矿区等段落的线路方案研究,探求在复杂外部控制环境下采用综合选线技术比选出最优线路方案的选线理念。在复杂环境条件下,应首先深入调查和分析铁路沿线自然地形、地质条件、建筑构造物等客观控制因素,并对沿线外部环境复杂性的特点予以总结和分类,针对性地采用相应的主要选线技术手段进行多方案比选,而后采用合理的评价指标比选出最优的推荐方案。实践表明,宝麟铁路勘察设计过程中应用综合选线技术有力地提高了选线质量和精度,科学合理地比选出最佳线路方案,良好地保证了推荐方案的安全、稳定、经济、合理性。

By route scheme research of unfavorable geological areas or mining areas on the railway from Baoji Second Power Plant to Linyou mine area （referred to as the Bao-Lin Railway） , the purpose of this research was to seek out an idea about how to use the integrated route selection technology comparing and selecting the optimum route scheme in complex external control environment. Then the research conclusions were as follows： under complex geological environment, first, the natural terrain, geological condition, building structures and other key objective factors should be deeply investigated and analyzed; then the complex characteristics of the external environment should be summarized and classified, and the relevant route selection technologies should be used to do multi-scheme comparison. Finally, the best recommendation scheme could be selected by adopting the reasonable evaluation indexes. Besides, it was found that with the application of integrated route selection technology in survey and design, not only the quality and accuracy of route selection of the Bao-Lin Railway were improved but also a scientific and reasonable optimum route scheme reasonability of the recommended was selected out, so the safety, scheme could be ensured. stability, economical performance and
