摘要
深地层、高地压、大断面巷道的支护方式应选择主动支护形式。本文根据加固拱和组合梁原理确定了采用锚网喷加锚索支护的支护方式,并由此计算出锚杆(索)参数和混凝土喷射一系列施工指标。
The tunnel supporting system of deep stratum, large ground pressure and big section area should choice active supporting style. In this paper, according to the principle of reinforced arch and combination beam the anchor-net-outbrust and bolt-cable support technique was adopted. And by this method, the parameters of bolt（cable） and construction data of concrete spraying were calculated.
