摘要
研究目的:大瑞铁路地质复杂,澜沧江大桥为大瑞线的控制工程之一,应先确定桥位,后选择线路方案,本文通过分析各拟选方案工程地质条件,得出最佳桥址方案。研究结果:王家庄与界牌桥位方案均跨越断裂带与不良地质,工程处理困难;霁虹桥位方案构造及岩性等地质条件相对较好,为最佳桥位。
Research purposes： The engineering geological condition of Dali - Ruili Railway is very complex and Lancang River Bridge is one of controlled engineering projects, so it is necessary to determine the site of Lancang River and then to determine the route selection of the railway. The analyses of the engineering geological conditions of all optional plans are made for the purpose of determining optimum bridge site Research results： According to the Wangjiazhuang plan and unfavorable geological zone, resulting in a difficuh construction. Jiepai The Jih plan, the bridge will cross some fauhs and ong plan is optimum and to which the bridge will cross a little better geological conditions zone of geological structure and lithology.
