带孔板灌浆套管连接受弯性能研究

Jianzhu Gangjiegou Jinzhan
节点作为装配式结构的关键传力部件，其力学性能直接影响整体结构的安全性与可靠性。文中提出了一种带孔板内钢管灌浆套管连接节点，通过对12个足尺节点开展三点受弯试验，系统研究了该节点的传力机制和破坏模式，深入分析了内管长度、宽厚比、开孔参数、灌浆料钢纤维含量等变量对节点承载力、刚度与延性的影响规律。试验结果表明：该类节点的主要破坏模式为灌浆料受剪滑移伴随内管断裂，其中内管长度、开孔形状和栓钉布置形式对节点受弯性能影响显著。基于弹塑性计算理论，结合节点实际应变分布特征，建立了该类节点的受弯承载力计算公式 ...

漏孔形态对GIS设备微水增长特性的影响

Gaoya dianqi
SF6气体泄漏是GIS设备最常见的故障之一，GIS泄漏发生时通常伴随内部水组分的增长。为了揭示不同漏孔形态对GIS设备微水增长特性的影响，选取了包含简单圆柱孔、台阶孔、锥形孔、直角孔及并排孔等7种漏孔形态，建立数值模型开展了多组分相变输运瞬态模拟。获得了GIS压力下降过程中不同漏孔内外部流场及水组分相变输运动态特性。结果表明，在相同的漏率规模下，漏孔结构越复杂，其出口位置羽流覆盖面积越小，外部冷凝水更容易进入漏孔内部；扩张型漏孔内会产生热力喉道等气动结构，该结构对液相水进入泄漏通道有明显的阻碍作用 ...
