高韦庄镇位于单县西南,地形较平缓,属黄河冲积平原,多年来连续发生地裂缝地质灾害,导致房屋开裂,土地失耕或减产,通过调查勘查,发现其地层12 m以浅存在厚度分布不均的膨胀土,而当地地下水位受季节影响常常在膨胀土内或其顶底板上下波动,导致膨胀土不断发生涨缩变形,引发当地地裂缝地质灾害的发生。可以通过碎石充填、清除、筏板基础等的地基加固处理措施进行防治。
高韋莊鎮位于單縣西南,地形較平緩,屬黃河遲積平原,多年來連續髮生地裂縫地質災害,導緻房屋開裂,土地失耕或減產,通過調查勘查,髮現其地層12 m以淺存在厚度分佈不均的膨脹土,而噹地地下水位受季節影響常常在膨脹土內或其頂底闆上下波動,導緻膨脹土不斷髮生漲縮變形,引髮噹地地裂縫地質災害的髮生。可以通過碎石充填、清除、筏闆基礎等的地基加固處理措施進行防治。

Gaoweizhuang town is located in southwest of Shanxian county.The terrain is relatively flat and belongs to the alluvial plain of the Yellow River.Geological disasters have been happened in many years, and have caused fissures in buildings,abandoned cultivation and yield reduction.Through investigation and exploration,uneven thickness of expansive soil has been found under the depth of 12m.When local under-ground water level is affected by season,it will sprout up and down in the expansive soil or in its top and bottom floor.Thus,expansive soil will rise,shrink and deform continuously,and geological disasters of ground fissures will happen.Through gravel filling,clearing,raft foundation and other foundation treat-ment measures,geological disasters in this area will be prevented and controlled.
