摘要
结合万州110kV输电线路混凝土电杆埋深段断裂事例和钢筋混凝土材料的特点与力学性能,以DL/T5154—2002《架空送电线路杆塔结构设计技术规定》为基础,分析得出了外荷载作用、混凝土碳化和钢筋锈蚀是引起钢筋混凝土电杆埋深段断裂的主要原因,并根据这些原因提出了相应的防治措施。
Combination with the crack case of buried segments of 1 lOkV transmission line concrete poles in Wanzhouand material characteristics and mechanical properties of reinforced concrete, base on DL/T 5154--2002 《The Technical Regulation of Design for Pole and Tower Structures of Overhead Transmission Line》, the main reasons why the depth sectionof reinforced concrete pole will be crack are analyzed, which includes the external load, concrete carbonation and steel eolxosion. And some corresponding prevention measures arc put forward.
