摘　　要：结合某引水工程始发井吊车梁的现场原型试验,分析不同荷载等级作用下大跨度T型吊车梁的变形、裂缝情况及承载性能。试验表明,荷载加载位置不同,其最大位移值和部位差异较大;在达到设计最大荷载时结构仍处于弹性阶段,但承载性能良好,能满足工程正常运行。Combined with the static test of the on-site prototype of the crane beam of a water diversion project,the mechanical characteristics and deformation of the structure under different load levels are analyzed.Tests show the maximum displacement value and location vary with different load positions.When the maximum load is reached,the structure is still in the elastic stage,and the structural bearing performance is good,which can ensure the normal operation of the project.
