阿勒泰黄泥滩供水工程隧洞对于城门洞断面的钻爆法施工段,采用一次喷锚支护与二次钢筋混凝土衬砌相结合的复合式衬砌方式。一次喷锚支护作为永久衬砌结构的一部分,根据地质情况的不同,在洞周一定范围内打系统锚杆并挂网、喷混凝土,使洞体围岩成为一个承载结构,这样可以减少作用在二次支护结构上的荷载,充分发挥围岩的承载能力。
阿勒泰黃泥灘供水工程隧洞對于城門洞斷麵的鑽爆法施工段,採用一次噴錨支護與二次鋼觔混凝土襯砌相結閤的複閤式襯砌方式。一次噴錨支護作為永久襯砌結構的一部分,根據地質情況的不同,在洞週一定範圍內打繫統錨桿併掛網、噴混凝土,使洞體圍巖成為一箇承載結構,這樣可以減少作用在二次支護結構上的荷載,充分髮揮圍巖的承載能力。

Altay Huangnitan power supply project tunnel adopts composite lining mode combining primary spray anchor support and secondary reinforced concrete lining in the drilling and blasting method construction section of city gate section. Primary spray anchor support is regarded as one part of permanent lining structure.System anchor is made in certain scope around the tunnel,nets are hung,and concrete is sprayed for making the surrounding rock of the tunnel into a bearing structure,thereby reducing load on the secondary support structure,and fully exerting the bearing capacity of surrounding rock.
