| Abstract: | Destruction reasons and treatment measures of shotcrete support of soil among piles inpile-anchor supportin northcold areas were discussedinthis pspre.Base onengineeringcases,the experimentof the crack-impeding effect of fiber fly ash shotcrete was carried out.It is proved that the“bi-adding”shotcrete support is feasible and effective. |
