雷击及工频续流条件下杆塔接地体热稳定性研究

Dianci bileiqi
为了研究雷击及工频续流条件下杆塔接地体动热稳定性及影响因素，首先采用ATP-EMTP计算了雷击及工频续流条件下流入接地装置的电流，将计算的入地电流作为杆塔接地体有限元仿真模型的终端条件，接地材料选用低碳钢和缆状、扁带状柔性石墨，分析在雷击及工频续流条件下接地体的温升及影响因素。研究结果表明：当雷电流及工频续流流入接地体时，接地体引下线处温升明显高于接地体其它位置，而且暴露在空气中的引下线温升最高；工频续流对杆塔接地体造成的温升大于雷电流的影响，且在相同幅值电流下，扁带状柔性石墨温升最高，低碳钢最低 ...

内置式锚箱索塔锚固区索力水平分力分配机理研究

Jianzhu Gangjiegou Jinzhan
索塔锚固区的受力分析通常采用实体有限元单元进行，然而由于其结构复杂、种类繁多，不易被一般工程设计人员使用。为此，结合某斜拉桥的实际工程案例，分析了内置式钢锚箱锚固体系的传力特点，提出了一种基于平面框架理论的简化计算方法，并利用非线性的分析方法建立了锚固区ANSYS有限元模型以修正公式。结果表明修正前简化公式计算结果与有限元模型计算结果之间的误差在10%左右；考虑到塔壁厚度、索塔计算高度以及锚箱侧板厚度的影响，使用折减混凝土弹性模量的方法来补偿和修正桥塔应力分布 ...
