摘　　要：隧道二次衬砌混凝土的施工质量与隧道结构的稳定性和耐久性息息相关,论文结合工程案例,分析了目前二次衬砌的质量缺陷及成因,并提出了混凝土本身质量、混凝土浇筑过程以及衬砌混凝土养护等方面的质量控制措施,包括混凝土的原材料、配合比设计以及运输、混凝土的泵送振捣、现场浇筑施工以及拆模养护等方面。The construction quality of tunnel secondary lining concrete is closely related to the stability and durability of tunnel structure.Combining with the support project, this paper analyzes the current quality defects and causes of secondary lining, and puts forward quality control measures in terms of the quality of concrete itself, the concrete pouring process and the lining concrete maintenance, including concrete raw materials, mix design and transportation, concrete pumping vibration, site pouring construction and mold removal maintenance.

关 键 词：隧道二次衬砌 质量缺陷 配合比设计 混凝土浇筑 混凝土养护
