摘要
通过一根25m预应力混凝土空心板的静载试验,测试了空心板在试验荷载作用下的工作状态,测定了结构的强度、刚度,将实际测试值与理论计算值进行了比较,并分析了空心板预加应力时的上挠度实测值偏小的原因,从而判断了空心板的安全承载力和使用条件。
By static load testing of prestressed concrete voided slab in 25m, there has been tested the working state of voided slab under action of test load, the strength and stiffness of structure, analyzed the reasons for upper determined deflection value getting small during voided slab prestressing, by contrast of practical tested value with theoretical computation one ,and judged the loadbearing capacity and operating conditions of voided slab.
