求翻译：在膨胀土地区，地下水多为上层滞水或裂隙水，随着季节水位的变化，可使膨胀土产生不均匀的胀缩变形，而当地下水位变化频繁或变化幅度较大时，不仅土的膨胀收缩变形往复，而且胀缩幅度也大，常常引起基础不均匀沉降，建筑物开裂、变形而破坏。是什么意思？

In the expansion of land area, mostly groundwater perched water or interstitial water, the water level changes with the seasons, can expand the non-uniform expansion and contraction of soil deformation, and when the water table or frequent changes in the magnitude of changes is large, not only the s
