摘要
为了便于混凝土电杆生产企业及其使用部门进行环形钢筋混凝土电杆抗裂强度及裂缝宽度的设计验算,本文依据相关规范,对设计方法和公式进行整理和总结,并列举工程实例进行计算说明,同时提出了提高抗裂强度和减小裂缝宽度的控制方法。
In order to facilitate the concrete pole production enterprises and user departments to design and check calculation of cracking strength and crack width of circular reinforced concrete pole, according to the relevant specifications, design methods and formula are summarized, and some engineering example calculations are shown. In addition, the control method for improving anti-crack strength and decreasing the crack width is put forward.
