摘要:
在拉林铁路雅鲁藏布江板块缝合带地区选线实践中，综合考虑工程地质条件、铁路工程可靠性、雅鲁藏布江桥位、隧道软岩大变形等因素，运用三维技术和层次分析法进行综合选线，总结出板块缝合带地区的铁路选线理念：（1）应用三维选线方法、多目标决策模型能增强选线的直观性和科学性；（2）尽量减少隧道工程，减少隧道软岩大变形或岩爆长度；（3）线路尽量选择在岩性较好的区域通过，降低隧道软岩大变形的风险；（4）线路尽量选择在被动盘通过；（5）尽量减少隧道埋深；（6）做好隧道软岩大变形设计预案，加强支护，防止隧道围岩大变形。
Abstract:
In Lhasa-Nyingchi Railway plate suture zone route selection, comprehensively considering the engineering geological conditions and the reliability of railway engineering, bridge location across the YarlungZangbo River, deformation of soft rock in tunnel and other factors, use three dimensional technology and AHP method, summing up ideas of railway line selection in the area of plate suture zone. The conclusions are as follows:(1) The application of 3D technology and multiple target decision making model can make the route selection more intuitive and more scientific.(2) As far as possible reduce tunnel engineering and large deformation of soft rock or rock burst length; (3) Choose good lithology area to reduce the risk of tunnel large deformation of soft rock; (4) The line is selected to be passed in a passive side; (5) Reduce the depth of the tunnel; (6) Make a design planof tunnel soft rock large deformation and strengthening support to prevent the large deformation of surrounding rock of tunnel.
