摘要
喷射混凝土是隧道工程中复合衬砌普遍采用的结构材料，它的质量好坏直接影响到整个隧道的结构受力、安全防护及耐久性。因此，对隧道中喷射混凝土施工质量的控制，有利于更好的满足隧道工程的技术特点。喷射混凝土的施工质量优劣，主要取决于喷射混凝土的强度、其与岩层的粘结力、喷射厚度及平整度等因素。
Abstract
Shotcrete is a type of struc-ture material that commonly used in composite lining of tunnel engineering, its quality wil di-rectly influence the whole tunnel’s structure stress, safety and durability.Therefore,to control the shotcrete construction quality in the tunnel is con-ducive to better meet the technical characteristics oftunnelengineering.Shotcreteconstructionquality, mainly depends on the strength of shotcrete, the injection of strata and the bond strength, depth and smoothness etc.
