一、光爆锚喷技术在引滦入唐工程的应用在引滦入唐工程中(见图),尤其足隧洞工程的建设,广泛地应用锚喷支护,而且大都作为永久支护,即所谓喷锚衬砌。锚喷混凝土工作量之大,隧洞之长,在全国还是不多的。整个工程七条隧洞,除大岭及南观隧洞,其他五条隧洞都采用了锚喷支 First, the light burst anchor spray technology in the project cited Luanhe into the Tang Dynasty Luan River project (see photo), especially the construction of full tunnel project, widely used anchor spray support, and most of them as a permanent support, the so-called spray Anchor lining. Anchor sprayed concrete workload, the tunnel length, not many in the country. The entire project seven tunnels, in addition to the Daling and Nanguan tunnels, the other five tunnels are used anchor spray branch
