【摘要】:正经过近7年建设,世界高海拔特长铁路隧道——青藏铁路西宁至格尔木增建二线新关角隧道于4月15日全线贯通。此间隧道专家介绍,这条平均海拔为3500米、全长32.6公里的"天路"隧道破解了多项世界技术难题。青藏高原是世界上海拔最高、面积最大、年代最新、地质构造最为活跃的高原。新关角隧道位于青藏高原地质板块挤压的结合部,具有高地应力、变形控制难度大等特点,共通过17个大、小断裂带,其中长达2355米的二郎洞断层束素有"隧道地质博物馆"之称。在隧道通过的灰岩富水地段,单口斜井日涌水量达到了13万方。
[Abstract]:After nearly seven years of construction, the new Guanjiao Tunnel of the Xining to Golmud railway between Xining and Golmud of Qinghai-Tibet Railway was built in April 15th. The tunnel experts here introduced. The 32.6-kilometer "Tianlu" tunnel, with an average altitude of 3,500 meters, has solved several of the world's technical problems. The Qinghai-Tibet Plateau is the world's highest altitude, largest area, and the latest of its kind. Xinguanjiao Tunnel is located at the junction of the geological plate of Qinghai-Tibet Plateau, which is characterized by high geostress and difficult deformation control. It passes through 17 large and small fault zones. The 2,355-meter long Erlangdong fault bundle is known as the "Museum of Tunnel Geology". In the water-rich section of limestone passing through the tunnel, the daily inflow of water from a single inclined well has reached 130,000 square meters.
