摘　　要：以清河水库除险加固工程中右岸泄洪洞新建隧洞为例,结合拉模与定型模板施工工艺特点,分析了两者在隧洞衬砌施工中设计及综合运用。实践证明:在隧洞衬砌施工中采用拉模与定型钢模板综合施工方案,既保证了衬砌混凝土质量,又节约了工期及异型模板的制作费用,促进了在实际工程中的应用。Taking the new tunnel in the right bank spillway tunnel of the Qinghe Reservoir Reinforcement Project as an example,and combining the construction technology characteristics of drawing formwork and set-shaped formwork,this paper studies the design and comprehensive application of the two methods in tunnel lining construction.The practice has proved that the comprehensive construction scheme of drawing die and set-shaped steel formwork is adopted in tunnel lining construction.The lining scheme not only guarantees the quality of concrete,but also saves the construction period and the cost of making special-shaped formwork,and promotes the application in practical engineering.
