昌平自行车赛场跑道是由四条对称的缓和曲线、两条对称的园曲线和两条对称的直线段构成的椭园盆形环状钢筋混凝土结构,建筑面积2830平方米。跑道座标测量精度为±3mm,跑道一周长度(即测计线)为333.33m+20mm,路面平顺,粗糙度要求适宜。施工测量技术和跑道面层与自行车轮胎的侧向动摩擦系数是本工程两大科研课题。北京市城建一公司同城建设计院合作,在跑道施工中首次使用高
The Changping Cycling Track is an elliptical oval-shaped circular ring reinforced concrete structure consisting of four symmetric relaxation curves, two symmetrical garden curves, and two symmetrical straight sections. The building area is 2,830 square meters. The accuracy of the runway coordinates is ±3mm, and the length of the runway (that is, the gauge line) is 333.33m+20mm. The road surface is smooth and the roughness requirements are appropriate. The construction measurement technology and the lateral dynamic friction coefficient of the track surface layer and the bicycle tire are the two major scientific research topics of the project. Beijing Urban Construction Company cooperated with the Urban Design Institute to use the first time in the runway construction
