| Abstract: | Based on the construction of Xingwangmao tunnel on SJS V section of the double track Taiyuan Zhongwei (Yinchuan) railway, the author presents the construction technologies and experiences for the shallow buried portal section, water rich and intense weathered mudstone section, alternative sandstone layers and roof ripping of No.3 inclined shaft. During the tunnel construction, the construction scheme was optimized based on the geologic conditions and the actual construction aims analysis and utilization of advantages of traditional construction methods. The optimized scheme has ensured the construction safety and construction schedule. |
