摘　　要：本文通过在三块楼板上施加均布荷载的试验,模拟某工程楼板改造后相应增设的矩形钢管搁栅及原有圆木搁栅在实际荷载作用下的受力情况。利用位移传感器测量的搁栅跨中挠度判断搁栅使用过程的安全可靠性,从而间接确定楼板改造方法的可行性。在试验基础上,回归出荷载-挠度曲线,回归曲线同试验曲线吻合良好。Based on experiment of three pieces of slabs under uniform distributive load,this paper simulates the stress condition of added steel tube joists and original wood joists,which below the reform slabs from a real project. In order to verify the indirect judgment reliability of the feasibility of slabs,the mid-span deflection of joists is measured by displacement sensor. The load-deflection curve is regressed on the basis of experiment,and it is in good agreement with the test curve.

关 键 词：楼板静载试验 搁栅受力情况 回归曲线
