【摘要】 随着社会经济的发展,现在很多偏远地区也需要进行输电线路的架设,输电塔基础按照传统的现浇施工方式会遇到各种施工条件的限制,施工难度变大。在这样的背景下,装配式基础出现了,装配式结构可以做到结构单件重量轻、现场组装方便,在施工过程中具有降低劳动力,安装方便简易,周期短,不需要像现浇基础那样现场大片浇筑混凝土,对运输困难地区更加适应。装配式混凝土台阶基础属于装配式基础的一种,基于装配式混凝土台阶基础的一种空心梁构件进行力学性能的理论和实验研究,通过对两者结果的对比,给实际工程应用提供参考。更多还原

【Abstract】 With the development of social economy,many remote areas now need to set up transmission lines.The transmission tower foundation will meet various construction conditions in accordance with the traditional cast-in-place construction method,and the construction difficulty will become larger.In this context,the assembled foundation has emerged.The assembled structure can achieve a light weight of the structure,easy assembly on site,low labor in the construction process,easy installation and short cycle,no need to be like the cast-in-place foundation.The concrete is poured on the site and it is more suitable for transportation difficult areas.The prefabricated concrete step foundation belongs to a kind of fabricated foundation.The theoretical and experimental study on the mechanical properties of a hollow beam member based on the prefabricated concrete step foundation provides a reference for practical engineering application by comparing the results.更多还原
