velocity and rail altitude difference 由图14可知:当隧道轨向高差峰值达到规范规定预警值2 mm/(10 m)时,平稳行车速度约为80 km/h；当隧道轨向高差峰值达到规范控制值4 mm/(10 m)时,平稳行车速度仅为20 km/h左右,若超过此速度行驶,则会产生舒适性问题,乘客行车舒适性降低；当地铁列车平稳行车时,其车速与隧道轨向高差峰值呈现负相关关系,隧道轨向高差......

of the mine. The four points were named No. 1, No. 2, No. 3 and No. 4, of which the absolute altitude were –88 m, –88 m, –77 m and –77 m, respectively, as shown in Figure 1. At each point, a Puxicoo RC-4... air was used in the normal direction of the surface of each measured point. We also put the Puxicoo RC-4 temperature recorder in the mine command center with the absolute altitude of 0 m to measure......
at the S201 Line K109+700, and the observation site is flat and wide (Figure 2). The geographic position of observation section is 119°58′50″, 50°35′25″, with an altitude of 612.2 m. It is an important part... 003. [7] LIU Jin-liang, JIA Yan-min. Temperature analysis of CFG pile composite foundation in high latitudes and low altitude island permafrost [J].
