摘要
在边坡治理工程中,需在搭设脚手架时以钢栈桥作为辅助支撑体。针对某水电工程地质条件复杂的实际情况,采用有限元法,分析了边坡治理工程钢栈桥的稳定性,得到了钢栈桥横梁和纵梁的应力和应变分布特性,确定结构受力和变形较大的位置,分析结构中比较危险的杆件,为设计与施工提供参考依据。工程实践表明,钢栈桥稳定性分析结果正确。
In slope treatment,the steel trestle is required to work as an auxiliary support while scaffolding is installed. Aiming at the complicated geological conditions of one hydropower station,the finite element method is applied to analyze the stability of the steel trestle for the slope treatment. The characteristics of the stress and strain distribution of the transversal and longitudinal girders of the steel trestle are derived,positions where the structural action and deformation are greater are determined. These provide design and construction with basis. The engineering practice proves that the results of the analysis on the stability of the steel trestle are correct.
