摘　　要：在隧道的复合式衬砌形式中,初期支护作为主要的承载结构,对于抑制围岩变形、防止坍塌及增强结构的可靠性和耐久性起着重要作用。隧道施工中一般采用钢架或格栅钢架与喷射混凝土及锚杆组成的初期支护,合理地选择钢架支护形式尤为重要。In the compound tunnel lining, primary support as the main load-bearing structure plays an important role for the inhibition of deformation of surrounding rock, prevention of collapse, and enhancement of the reliability and durability of structures. Primary support adopted in general is the combination of steel frame or grid frame and shotcrete and anchor rod. It is particularly important to choose the right type of steel frame.
