【摘要】 新建格尔木至库尔勒铁路在阿尔金山北缘断裂山前段,线路平面位置受高程约束,区域内地质构造复杂,不良地质灾害危害严重构成了控制线路方案的主要工程地质问题,通过综合勘察法,详细调绘了该地区构造及地质灾害特点,在充分总结汲取山区铁路综合选线技术经验的基础上,提出了阿尔金山北苑断裂山前段选线定线技术原则,选取地质条件具有优势的桥方案跨越该地区,选线效果显著,同时也为山区类似地质条件地区地质选线提供借鉴。更多还原

【Abstract】 New Golmud to Korla railway in the northern margin of Altun Mountains rupture front line,bounded line position by the elevation plane,complex geological structure in the region,seriously harmful geological disasters constitute the main engineering geological problems in the rail line control.Through comprehensive survey method,the structure and characteristics of geological disasters in this region was expounded in detail.After drawing a comprehensive summary in full mountain railway line selection on the basis of technical experience,Altun mountain front line selection Beiyuan fracture alignment technical principles was proposed.By selecting advantageous geological conditions across the bridge program the area,line selection effect is significant and can be reference for the geological line selection where mountainous region geological conditions are similar.更多还原
