| Abstract: | Being soil cave, the entrance section of Fuxi-Jinxin tunnel is the difficulty area in construction. The soil cave construction technique regards the soil slope support, reinforcing the mouth of the cave and steel arch frame belt, grouting & mesh combined support in the cave as a organic whole. The adopted technique and obtainable effects in construction are introduced in detail based on construction practice. |
