Take a 20 m hollow plate beam as an example, the static load experiment was conducted, and the experimental data about overall displacement, cross-section strain and the crack were analyzed carefully. The re-sults show that;l) its stiffness satisfied the design code. 2) the actual measured strain take on linear variety along the section height, which match the plane cross-section assumption; and the stress experiment coefficient is 0. 562, which satisfied the testing specification. 3 ) there is no crack occur under the last experiment load case. Which show that the hollow plate beam satisfies the design code.%进行了跨径为20m的预应力混凝土空心板静力载荷试验,对梁的整体挠度、梁截面应变以及抗裂性试验数据进行了详细分析.结果表明:(1)该梁的刚度满足设计要求；(2)实测应变沿截面高度呈线形变化,符合平截面假定；应力校验系数为0.562,满足试验规范的要求；(3)在最大级试验荷载作用下,未发现有横向裂缝产生,试验空心板梁满足设计要求.
