接缝间距 meaning in Chinese

spacing of joins
spacing of joints

In this paper , a three dimensional finite element analysis has been used to analyse the loading stress of utw pavement . the critical loading position of utw plate and the rules of the effect of the joint spacing of plate , the thickness of overlay , ec / es and the interface conditions between concrete overlay and existing ac on the stress are provided
本文采用三维有限元法分析了utw路面荷载应力，确定了路面板的临界荷位，得出了板接缝间距、厚度、板与地基模量比( ec es )和层间接触状况对应力的影响规律。
