地下结构在火力发电厂土建结构中占据重要地位,其结构设计复杂且工程量巨大,长期以来成为设计优化关注的重点。采用合理的计算方法,准确模拟结构实际受力,成为优化设计和降低工程造价的关键。本文以地下输煤隧道这一简单结构入手,采用弹性地基理论和有限元分析方法,针对不同的边界约束、不同的单元类型和不同的地基刚度分析结构受力的变化,探索较为符合实际的计算方法,为设计提供参考。
Underground structures occupy an important position in the civil structure of thermal power plants, and their structural design complexity and huge amount of engineering have long been the focus of design optimization. Using reasonable calculation method to accurately simulate the actual structure of the force, as the key to optimizing the design and reducing the cost of the project. Based on the simple structure of underground coal transportation tunnel, this paper uses elastic foundation theory and finite element analysis method to analyze the change of the force of the structure with different boundary constraints, different unit types and different foundation stiffness to explore the more realistic calculation Method, for the design of reference.
