余震及强降雨条件下千枚岩隧道施工塌方预防

摘要

通过试验研究了千枚岩的力学性能,结合隧道本身的特殊性,分析了在余震、强降雨等条件下千枚岩隧道施工塌方的原因,进而给出了相应的塌方预防措施,为类似条件下的千枚岩地段施工积累了经验。%This article studies the mechanical performance of the phyllite through test. Combining with the specialty of the tunnel itself, it analyzes the causes of phyllite tunnel construction collapse under the condition of aftershoeks and heavy rain, and shows c
