摘　　要：某核工程采用重混凝土作为钢板混凝土填充材料,在钢板混凝土墙与钢筋混凝土底板的节点位置采用插筋连接。对于重混凝土中钢筋的锚固性能,破坏特点等尚缺乏理论和试验支撑。本试验通过对试件荷载位移曲线、钢筋荷载应变曲线的分析,验证在单调拉力作用下,锚入赤铁矿重混凝土内钢筋的受力情况,以及是否产生滑动现象。Heavy concrete is used as the filling material of steel plate concrete in a nuclear project,and the joint between steel plate concrete wall and reinforced concrete base plate is connected by dowel bars.There is still a lack of theoretical and experimental support for the anchorage performance and failure characteristics of reinforcement in heavy concrete.Through the analysis of the load displacement curve of the specimen and the load strain curve of the reinforcement,this test verifies the stress of the reinforcement anchored into the hematite heavy concrete under the action of monotonic tension and whether there is sliding phenomenon.
