摘要
凫溪—金溪隧洞进口段的洞口段为土洞,是施工中的难点。土洞施工技术把土边坡支护、洞口加固、洞内钢拱架锚喷网联合支护视为一个有机整体。根据施工实践,详细介绍了施工中采取的施工技术以及达到的施工效果。
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.
