鲁豫交界的曹县黄河故道地区，地势较高的自然堤堤缘区是地裂缝等地质灾害的高发区。地裂缝主要由地表厚粘土层干湿胀缩产生，有一定的隐蔽性，并受地形和大气影响。地下水动态变化对地裂缝影响不大。地表裂隙张力的直接作用、建筑物的非均质土地基不均匀沉陷等因素的存在共同导致了该区民房开裂。可以采取加固地基和搬迁避让等方法进行防治。
魯豫交界的曹縣黃河故道地區，地勢較高的自然隄隄緣區是地裂縫等地質災害的高髮區。地裂縫主要由地錶厚粘土層榦濕脹縮產生，有一定的隱蔽性，併受地形和大氣影響。地下水動態變化對地裂縫影響不大。地錶裂隙張力的直接作用、建築物的非均質土地基不均勻沉陷等因素的存在共同導緻瞭該區民房開裂。可以採取加固地基和搬遷避讓等方法進行防治。

In old course of the Yellow River in Caoxian county,high natural dam area is a high happening area of geological disasters,such as ground fissures.Ground fissures are mainly caused by dry,wet,ex-pansion and contraction of thick clay layer surface.It has certain concealment and be affected by terrain and atmosphere.Groundwater dynamic changes will affect ground fissures weekly.Direct effect of surface ten-sion fracture,inhomogeneous settlement of foundation of heterogeneous soil of buildings have caused ground crackings together.Foundation reinforcement,moving and avoidance can be carried out for preven-tion and control.
