一、前言3000米障碍跑的跑道有多种设计方法。把水池设在第二弯道内突沿内侧的这种方法,由于新弯道较原400米跑道的弯道短,所以通常称为“小弯道”。这种方法目前在国内外采用得最为普遍。但是,在国内的一些有代表性的文献中,对这种设计方法的记载不够详尽,计算数据亦不统一。因此,有必要对小弯道的结构和数据作重新探讨。

First, the preface There are a variety of design methods runway runway 3000 meters obstacle. This method of locating the pool in the second curve along the medial side is often referred to as a “small curve” because the new curve is shorter than the curve of the original 400-meter runway. This method is currently the most widely adopted at home and abroad. However, in some domestic representative documents, the design of such a method is not exhaustively documented, and the calculated data are not uniform. Therefore, it is necessary to re-examine the structure and data of small curves.
