For the tunnels in cold region, because of the rock heaving role, lining structure of tunnel is prone to cracking, collapse and other quality problems which directly threat the operational safety. The quality detection in construction can timely detect, find and treat the quality problems during construction, to achieve the purpose of prior control, reduce or eliminate unnecessary security risks, and ensure the quality of tunnel construction.%寒区隧道，由于围岩冻胀作用，隧道存在衬砌结构易出现开裂，坍塌等量问题或隐患，直接威胁营运安全。在施工中进行质量检测能够及时检测、及时发现、及时处理施工过程中的质量问题，达到事前控制的目的，减小或杜绝不必要的安全隐患，确保隧道施工质量。
