高强部分预应力混凝土电杆的连接设计研究

A Studyon Connection Design of the Partial Prestressed High Strength Concrete Pole

活性粉末混凝土(RPC)是一种超高强度、超高性能的高致密水泥基复合材料,具有非常优异的力学性能和耐久性,是制作高强部分预应力混凝土电杆的理想材料。目前这种电杆杆段的设计理论已经成熟,为推广应用现开展电杆杆段间及电杆同基础间连接方式的设计研究,并运用ABAQUS程序对所设计的刚性法兰连接方式进行数值模拟,分析局部受力情况,从而得到适合超高压线路使用的部分预应力RPC混凝土电杆的连接方式。

Reactive Powder Concrete（ RPC） is a new material with ultra high strength,high toughness,ultrahigh durability and excellent volume stability. It is the best material to make EHV partial prestressed high strength concrete pole. The study of design theory of this pole has been very mature so far. To apply practically,the thesis studied and resolved the problem of connection on the section of the partial prestressed RPC pole,and utilized ABAQUS to analyze the stress state of rigid flange and the partial prestressed RPC pole. Therefor it obtained compatible connection-mode of EHV partially prestressed high strength concrete pole.
