During processing the pumping station groundwork of the collapsibility loess in ningxia south mountainous area , we used the method of soil - exchanging to designing , constructing and collapsibility distortion observation on thickly layer , and found a conclusion that soil - exchanging on processing bad geological hydraulic engineering groundwork was a method of less investment , shorter project time and good effect 摘要通过对宁夏南部山区严重湿陷性场地建设扬水泵站的地基处理，和对换土法在深厚层湿陷性地基中设计、施工、沉降变形观测等的论述，得出水利工程在处理地基不良地质问题中，换土法具有投资少、工期短、效果好的结果。

Or , the project cannot play its due efficiency and even can be discarded in the midway . this will cause the great waste . the water intake of ningxia guhai pumping engineering and the water intake of yuejin channel on yellow river have been moved forward several times because of the silt 位置选择适宜，建筑规模合理，则可以节省工程投资，达到预期效果；位置选择不当，则有可能造成该工程不能发挥其应有的功效，甚至会中途废弃，造成极大的浪费，此现象不乏实例，如宁夏的固海扬水取水口，跃进渠黄河取水口因泥沙淤积就曾几次前移。
