某电厂输煤栈桥结构加固设计

Structural Retrofit Design for the Coal Handing Trestle of an Electricity Generating Station

某电厂输煤栈桥的楼屋盖板、柱及桁架杆件混凝土强度偏低,部分桁架杆件存在裂缝、局部缺陷,钢筋外露锈蚀。为确保该栈桥结构继续安全使用,在对原结构承载能力进行校核计算的基础上给出了合理有效的加固设计方案及加固措施。

The concrete strength of floor plates, columns and truss member bars of the coal handing trestle of an electricity generating station are low, and some cracks, partial impairment and steel bar corrosion on some truss members exist. Based on the calculation for the carrying capacity of original truss structure, the rationally effective retrofit design and corresponding retrofit measurements are presented in order to assure continual safety work.
