摘   要：近年来在隧道二衬混凝土的回弹检测中，时有因养护不到位而影响混凝土质量，或因养护方法不当导致二衬混凝土表面开裂等情况的出现。针对此情况，固西公路炸嘴山隧道研发了蒸汽覆模养护技术，系统主要由养护罩、蒸汽系统和控制系统三部分组成，实现了对隧道衬砌混凝土采取蒸汽高温养护和标准养护两个阶段，取得了很好的效果。

Abstract: In springback inspection for tunnel lining concrete in recent years, the situation of tunnel lining concrete surface cracking is produced by not reaching curing or improper curing method. Aiming this situation, steam mulching model curing technology is researched in Guxi highway Zhazui mountain tunnel, that system mainly consists three parts of curing cover, steam system and control system, two stages that contains steam high temperature and standard curing are reached for tunnel lining concrete, which can achieve good effects.
