最小曲线半径(R_(min))是铁路设计的主要技术标准之一,它的容许值大小取决于多种因素。从节约基建投资出发,容许值小则更易于与地形条件吻合,在复杂条件下,可显著节约工程投资。但从运营角度来看,曲线半径过小,往往会给运输工作带来一些不利影响,这是众所公认的事实。如何综合考虑,尽量做到两者兼顾,这便是工程技术人员在设计阶段所思考的问题之一。有关最小曲线半径问题,在我国已有不少同志进行过研究,取得了很多有价值的成果。本文仅就近年来的变化,提出浅见,以期抛砖引玉。
The minimum curve radius (R min) is one of the main technical standards for railway design. The allowable value depends on many factors. Starting from saving capital investment, the smaller the allowable value is, the easier it is to match with the topographical conditions. Under complicated conditions, significant project investment can be saved. However, from an operational point of view, it is generally accepted that the curve radius is too small, which tends to bring some adverse effects to the transport work. How to consider synthetically, try to do both as far as possible is one of the questions that engineers and technicians think in the design phase. Regarding the issue of minimum curve radius, many comrades in our country have conducted research and made many valuable achievements. This article only on the changes in recent years, made humble opinion, with a view to initiate.
