摘　　要：某工程为预应力预制装配式风电塔架,其塔身坐落于环形基础现浇段,现浇段采用弧形钢模板拼接成环后进行混凝土浇筑。由于平面模板的计算模式不符合模板实际受力特点,故引入弹性力学平面应变问题的求解,对钢模板的承载力进行了较为精确的计算,得到了理想的结果,也为日后钢模板的设计和应用提供相关参考。A prestressed prefabricated wind power tower was used in a project and its tower body was constructed on the cast-in-situ section of annular foundation.The cast-in-situ section was assembled into an annular formation by an arc-shaped steel formwork and then the concrete was poured.Since the calculation mode of the plane formwork did not conform to the actual force characteristics of the formwork,the solution of the plane strain problem of elastic mechanics was introduced to calculate the bearing capacity of the steel formwork more accurately.Ideal results were achieved and relevant reference can be provided for the design and application of steel formwork in the future.
