标准田径场直道和半圆交接处的坡度研究

Study of Gradient at Junction of Straight Lane with Semicircle of Typical Track and Field Stadium

田径场的纵向、横向坡度和平整度IAAF有严格规定,半圆与直道交接处的坡度处理,需要纵、横坡度及平整度兼顾。该文以半径为36.5 m的8道400 m标准田径场为研究对象,经研究确定一个坡度值,以供设计和施工时参考。

The longitudinal,transverse gradients and levelness IAAF are strictly stipulated.The gradient treatment at the junction of semicircle with straight lane is required to take into account both longitudinal,transverse gradients and levelness.Taking the radius 36.5 m of 8-lane 400-m typical track and field stadium as the studying object,the article determines a gradient value to be referred for the design and construction.
