天山独库公路系国道217的南段。它北起天山北麓的独山子,南至天山南麓的库车城,依山傍水,横穿天山,蜿蜓达530公里。独库公路在70年代修筑期间,沿线曾多处发生过泥石流,自1983年正式通车之后,泥石流更是连年爆发,经常冲毁桥梁,堵塞涵洞,埋没公路,阻断交通,给天山南北之间的客货运输和山区资源的开发造成了严重的危害。经实地考察得知,在独库公路沿线直接给公路造 Tianshan Autonomous Region Highway State Road 217 South. It is north of the Tushan Mountain north of Dushanzi, south of Tianshan south of Kuche City, Yishanbangshui, crossing the Tianshan, meandering 530 kilometers. During the construction of the Autonomous Region Highway in the 1970s, landslides occurred along the route. Since its official opening to traffic in 1983, the debris flow has even been erupted in successive years. It often breaks bridges, blocks culverts, inundates roads and blocks traffic to the north and south of the Tianshan Mountains The passenger and freight transport and the exploitation of mountain resources have caused serious damage. After field investigation, we learned that roads are directly made to the highway along the Autonomous Highway
