| Abstract: | The reason of tunnel collapse is analyzed.The technical parameter of cement-silicate grouting reinforce- ment and support of surrounding rock as well as its corresponding technology are discussed.The supervising data shows that the surrounding relative displacement of collapse plot of the tunnel after treatment is smaller,which ex- presses that the whole surrounding rock is stable.The results meet the standard of highway tunnel construction techniques. |
