页岩陶粒混凝土叠合板原型堆载试验研究

Imposed Load Test of Full-scale Shale-ceramsite Concrete Composite Slabs

对4块足尺页岩陶粒混凝土双向叠合板进行了静力堆载试验,并对其变形特征、破坏形态和裂缝开展情况进行了分析;同时对2块足尺页岩陶粒混凝土单向叠合板进行了静力堆载试验,以研究叠合面的滑移特征。结果表明:半普通-半陶粒混凝土叠合板和全陶粒混凝土叠合板均具有良好的整体性和较高的刚度及承载力,能够作为结构楼板使用;同时通过对单向板板侧应变的分析,叠合面不会出现滑移。

Four full-scale two-way shale-ceramsite concrete composite slabs were subjected to static loading test,and their deformation characteristics,fracture morphology and crack behavior were analyzed.At the same time,the static loading test was carried out on two full-scale one-way shale-ceramsite concrete composite slabs to study the slipping character of the laminated surface.The results show that semi-ordinary semi-ceramsite concrete slabs and all-ceramic concrete slabs both have good integrity and high stiffness as well as bearing capacity,and can be used as structural slabs.At the same time,through the analysis of strain on the side of the slabs,the laminated surface will not slip.
