Abstract
According to the engineering geological conditions of the Chadigou long tunnel of Kayang Highway,the causes of collapse in the sec-tion were analyzed,and a safe and reliable collapse treatment scheme adapted to the actual situation of the site was proposed.The type of"pipe shed safety protection first,steel arch followed by support"was adopted to strengthen the construction parts of the collapse area.Finally,the caving concrete backfill is carried out,which achieves the expected effect and lays the foundation for the opening of the whole line of Cay-ang Highway,which is worthy of popularization and application for similar projects.关键词
