摘要
结合新建双线铁路太原至中卫(银川)线SJS-V标兴旺峁隧道的施工实践,重点介绍洞口浅埋段、富含饱和水的强风化泥岩、砂岩平互层段及3#斜井进正洞挑顶段的施工方法和经验;在施工过程中,通过对具体地质条件的分析,在继承传统施工方法优点的基础上,结合不同的施工内容,对各个具体施工方案进行优化,确保了施工安全和工期要求。
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.
