| 摘 要： | 小卡子隧道是连接九龙县城和石棉县城的一条便利通道,它是连接S215和S211的绿色保障,九龙和石棉之间是海拔高度4 000 m以上,九龙县城周边为高原宽谷丘陵地区,地势起伏较大。九龙至周边沿线不良地质和特殊褶皱构造发育,其中冰雪害几乎每年冬春都发生,且影响线路较长,其它地质灾害也时常暴发,致使交通事故频繁发生,成为制约九龙县发展,因而急需要对线路进行改造,拟建连接九龙县至石棉县小卡子隧道即为公路改建工程。

| Abstract: | The Xiaokazi Tunnel is a portable road to connect Jiulong and Shimian Counties. It is green protection to connect 5215 and S211. The altitude is above 4000m between Jiulong and Shimian. At Jiulong county surroundings is the plateau dale and upland region and the terrain is undulating seriously. For the growth of the poor geology and special drape structure from Jiulong to the surroundings, the damage caused by ice and snow occur almost every year and influence the line for a long time. The other geological disasters are frequent outbreaks which causing traffic accidents occur frequently, as a constraint to the development of Jiulong County. And thus an urgent requirement on line transformation, it proposed to build a Xiaoka tunnel to connect Jiulong County and Shimian counties, so it calls the highway reconstruction oroiect. |
