摘　　要：基于结构力学、材料力学,对高边坡脚手架的横向水平杆、纵向水平杆、立杆和连墙件等部位分别进行了内力计算,选取最不利的内力组合情况进行构件承载力分析,分析了对其安全性影响最大的应力和挠度,并应用于锦屏一级水电站高位危岩体高陡边坡双排支护排架。结果表明,脚手架应力变形的各项指标控制在规范允许范围内,说明双排钢脚手架结构安全。Based on structural mechanics,mechanics of materials,this paper calculates the internal force for these parts of scaffold,such as lateral horizontal pole,longitudinal horizontal pole,upright tube,connecting tube and so on,and selects the most unfavorable component of internal force to check the bearing capacity of the structure,analyzes the deflection and stress which has the biggest influence on the safety of the structure,which are used in the scaffold analysis in high slope for Jinping first stage hydroelectric power station. The result shows that the each index of the deformation and stress of scaffold is controlled within the specification allowing ranges,which explains that the double row scaffold structure is safe.
