摘要
针对高压输电线路中钢筋砼电杆端部裂缝的工程问题，探讨了电杆端部裂缝的机理，研制了预应力钢环，有效地控制了电杆端部的裂缝，并进行了实验验证．
The mechanism of end cracking occurred at reinforced concrete mast for high voltage transmission is investigated.A kind of prestressed steel collar is developed so that the end cracking of the pole is prevented effectivelly,which is verified by experiment.
