| 摘 要： | 针对30m先张预应力混凝土空心板的中腹板在预制过程中厚度常常较薄或透空的现象，运用了简、明力学方法对缺陷空心板纵向抗剪受力和顶板强度进行了结构安全验算、分析，并通过静载试验测试了缺陷空心板的刚度。在此基础上，做出了缺陷空心板的结构性能评价。

| Abstract: | In view of the phenomenon which the thickness of the web in 30 m first prestressed con- crete hollow slab is often thin or permeable in process of precasting, a simple mechanical method was used to do the structure safety check and analysis of the longitudinal shearing stress and roof strength for the defected hollow plate. And the stiffness of the defected hollow plate was tested through the static load test. On this basis, structural properties of the defected hollow plate were evaluated. |
