补充资料:冻土融沉
      冻土融化时的下沉现象。包括与外荷载无关的融化沉降和与外荷载直接有关的压密沉降。
  
  冻土融化时发生着两个相反的过程:压密和膨胀。①冻土中的各种冰融化后体积缩小,使土因自重下沉;冰变成水后通过孔隙逐渐排出,使土压密而进一步下沉。②土粒及其集合体在融化时由于水化作用而膨胀。通常情况下,冻土融化时的压密大于膨胀,故产生融化下沉。当整体冷生构造的冻土融化时,其融沉量一般不大。但层状和网状冷生构造的冻土融化时,常有明显的沉降,有时会发生突陷。当冻土的融化速度很快时,会出现冰变成水的速率大于水能从土中排出的速率,从而使土中的孔隙压力增加,常造成斜坡和各种建造物的不稳定。融沉是多年冻土区建造物破坏的主要原因。在天然情况下,冻土的融沉会形成各种热喀斯特现象(见冰缘地貌)。
