错台【faulting of slab ends】。错台现象不但会对新铺的沥青混凝土路面平整度产生影响，而且完工后新铺的沥青混凝土路面也会在此处形成裂缝，严重影响工程质量，因此必须进行处理。错台【faulting of slab ends】指的是在水泥混凝土路面的接缝或裂缝处，两板体产生相对竖向位移的现象。常年的车流可能造成相邻旧混凝土板高低不平，形成错台现象。
Based on the force analysis on longitudinal dislocation of shield segment, we deduce the calculation formula of longitudinal dislocation which relate to the driving force of jacks, the adjacent segments, the geologic strata circumstance and so on.
