| 摘 要： | 对环形截面混凝土电杆纵裂产生的主要原因进行了研究,认为:主要由于压应力、温度及干缩应力的共同作用,使电杆中有些点处于压—拉双向应力作用状态,导致纵裂产生。并通过试验,对电杆受力情况进行了理论分析,从而提出了防止电杆纵裂的4点措施。

| Abstract: | The main cause to produce longitudinal cracks on annular section concrete poles is studied. It is considered that some points in the pole are in the state of compression - tension bidirectional stresses due to combined actions of compression, temperature and dry - shrinking stresses,and this state leads to form longitudinal cracks. The theoretical analysis of force enduring state in the pole is made through tests,and 4 measures to prevent the longitudinal cracks of pole are submitted. |
