| Abstract: | During the construction of the left tube of Bixi tunnel on Tai-jing highway, huge cracks and deformations occur to the shotcreting layers of the primary reinforcement and the situation tends to grow more intense. On basis of such situation, the article analyses on the reasons for the huge deformations and presents the technical schemes and construction measures taken to overcome the situation, as well as the effects of the measures. |
