沪昆客专(云南段)野火芽隧道位于云贵高原剥蚀构造丘陵区,在进口段D1K0161+547-D1K1061+568段拱顶覆盖层浅,属于浅埋偏压隧道,浅埋段施工技术方案的选择对隧道安全顺利进行有着十分重要的意义。本文以野火芽隧道浅埋段施工的成功经验为例,介绍下隧道浅埋施工方案、施工措施及注意事项,希望可以为类似浅埋偏压隧道提供参考。
Shanghai-Kunming Specialties (Yunnan section) Wildfire bud tunnel located in the Yunnan-Guizhou Plateau denudation tectonic hilly region, in the import section D1K0161 +547-D1K1061 +568 section of the vault cover shallow, is shallow buried tunnel, shallow section of construction technology program The choice of tunnel security is very important. This paper takes the successful experience in the construction of shallow burying tunnel of wild fire bud tunnel as an example to introduce the shallow tunnel construction scheme, construction measures and precautions, hoping to provide a reference for similar shallow buried tunnel.
