摘要
为研究地下工程格栅支撑这一新型支护结构的力学性能,进行了一系列格栅支撑的小比例结构静力加载试验,分析了格栅支撑的承载力性质和破坏特性。结果表明,格栅支撑是一种刚度可以调节、结构受力合理、强度安全可靠、符合现代支护原理的优良支护结构。
In order to investigate the mechanical performance of lattice girders, a series of small scale static load tests are carried out and the loading properties and failure behaviour are analysed. The results confirm that lattice girder is a good support con- structional element, for its rigidity is changeable, its structure reasonable, and its strength reliable. Moreover, its working principle conforms to the modern support theory.
