随着电力建设的发展,为了节省占地和有效利用场地,在我们的发、变电工程中,今后将日益更多地采用挡土墙结构。挡土墙,按其功能,一般分为边坡挡土墙与抗滑挡土墙两大类。我们工程中的挡土墙,大多为边坡挡土墙。本文,在总结实践经验的基础上,对寻求挡土墙的经济断面进行探讨。考虑到已用的大多是砌石挡土墙,而这种结构又具有就地取材,易于施工的特点,今后仍将有其被采用的广泛性,故以此为题进行讨论。为了叙述的方便,将挡土墙结构的有关部位定名如图1所示。
With the development of electric power construction, in order to save space and effectively use the site, in our development and substation projects, we will increasingly use retaining wall structures in the future. Retaining wall, according to its function, is generally divided into two categories: slope retaining wall and anti-sliding retaining wall. Most of the retaining walls in our project are slope retaining walls. In this paper, on the basis of summarizing practical experience, we will discuss the economic section of the retaining wall. Considering that most of the masonry retaining walls that have been used are characterized by local materials and ease of construction, there will still be widespread adoption in the future. For the convenience of description, the relevant parts of the retaining wall structure are named as shown in FIG. 1 .
