前言 1962年至1964年我院根据部令完成了电杆标准化工作的通信、自动閉塞及电力电杆三套标准图和技术条件二項任务。在电杆标准化工作中,我們对鋼筋混凝土电杆各項力学性能及設計計算理論等方面也作了一些初步研究,提出了一些看法,虽然这些認識很肤浅,但考虑到目前路內这方面发表的有关資料尚很少,并考虑到近年来大力貫彻节約木材措施,木电杆使用将受到很大的限制,預計将来鋼筋混凝土电杆势必完全替代木杆。故将电杆設計中的有关資料如試制試驗(由鉄道科学研究院、丰台桥梁厂,专业設計院协作进行了八种类型的电杆試制試驗)成果,刚度、挠度計算和設計中有关問題等陆續发表。由于我們工作不够深入,經驗不足,并限于水平,不妥之处在所难免,故仅能起抛砖引玉作用,尚請不吝赐教。
Preface From 1962 to 1964, our hospital completed the tasks of standardization of power poles, automatic blockage and three sets of standard diagrams and technical conditions of power poles according to the order. In the standardization of electric pole, we made some preliminary studies on various mechanical properties and design calculation theory of reinforced concrete poles, and put forward some opinions. Although these understandings are superficial, considering the current publication of this road Of the relevant information is still very small, and taking into account the efforts to implement wood-saving measures in recent years, the use of wooden poles will be greatly limited, in the future is expected to be completely replaced by poles of reinforced concrete poles. Therefore, the pole design of the relevant information such as trial production test (by the Road Research Institute, Fengtai Bridge Factory, Professional Design Institute collaborative eight types of pole trial) results, stiffness, deflection calculation and design issues One after another published. As we are not deep enough, inexperienced and limited to the right place, it is inevitable that we can only act as a trigger for further improvement. Please let us know.
