摘要
水电项目施工中,经常遇到边坡岩层不够稳定等不良地质情况,为防止因边坡不稳定造成的危害,工程中经常搭建大量排架,并架设钢栈桥作为钢管排架的基础,因此开展钢栈桥基础稳定性研究具有重要理论意义及工程价值。本文以某厂房边坡危岩体治理工程为背景,分析不同因素对钢栈桥基础力学性能的影响,通过理论分析和有限元数值模拟相结合的方法,对钢栈桥结构型式和截面尺寸进行优化设计,给出工程常用跨度和荷载下结构的截面选择。
In the construction of hydropower projects, unfavorable geological conditions such as insufficient stability of the slope rock formation are often encountered. In order to prevent the damage caused by the unstable rock slope, a large number of trusses are often built in the project, and the steel trestle bridge is erected as the foundation of the steel pipe truss. Therefore, the research on the stability of the steel trestle foundation has important theoretical significance and engineering application value. This paper takes the dangerous rock mass control project of the right bank slope of a factory as the research background, analyzes the influence of different factors on the mechanical properties of the steel trestle foundation, through the combination of theoretical analysis and finite element numerical simulation, the structural design and section size of the steel trestle are optimized. According to the calculation results of the optimized design, the section selection of the structure under common span and load is given.
