结合《火力发电厂土建结构设计技术规程》对单跨框架结构的适用条件及要求,阐述了本工程在充分满足工艺专业布置的前提下,用三维空间分析法及纵、横两个方向的平面分析验证,证明主厂房采用单跨框排架结构满足了结构强度、稳定、变形及抗震等的计算要求,同时提出提高抗震构造措施、增大柱截面、降低轴压比等途径来保证结构安全度,并建议本工程主厂房采用汽机房与煤仓间构成的现浇钢筋混凝土多层单跨框排架结构形式。
Combining with the applicable conditions and requirements of single-span frame structure of “Technical Code for Design of Civil Structure of Thermal Power Plants”, the paper expounds that on the premise of fully meeting the layout of technology specialty, this project uses three-dimensional space analysis method and the vertical and horizontal plane The analysis and verification prove that the main workshop adopts the single-span frame structure to meet the calculation requirements of structural strength, stability, deformation and seismic resistance. At the same time, some measures such as improving seismic structure measures, increasing column section and reducing axial compression ratio are proposed to ensure structural safety Degree, and suggested that the main workshop of this project adopt the form of cast-in-place reinforced concrete multi-layer single-span frame structure formed by steam engine room and coal bunker.
