The key of maintaining the tunnel stability lies on how to deal with the advance core soil ahead of working face, which is obtained on basis of analysis on the problems in high speed railway tunnels with big crosssections in soft surrounding rock or soil. Fullface prereinforcing method by fiberglass bolts can enhance the equivalent rigidity of the advance core soil and control the deformation of the advance core soil, so that arch effect can play its role naturally and assure the excavation safety.

总结分析了目前高速铁路大断面软弱围岩或土质隧道施工中存在的问题，认为如何处理好掌子面前方的"待挖核心体"是控制此类隧道整体稳定性的关键，运用沿隧道纵向全断面预加固的易切削玻璃纤维锚杆来提高"待挖核心体"的等效刚度，控制"待挖核心体"的变形，使得隧道周边的拱效应能自然发挥作用，可以保证隧道能够全断面安全、顺利开挖掘进。
