CSAMT法在泰安市浅层地下水调查中的应用

Application of CSAMT Method in Investigation of Shallow Groundwater in Taian City

泰安市范镇地区为开发利用地下水资源,选取CSAMT测深方法进行探测,勘探目的层为200 m以浅,选用频率5~9600 Hz,采集时间30 min,共布设井位三处。经钻探及抽水试验,平均出水量为30 m^(3)/h。结论表明,在高密度电法探测深度不够、电测深效率较低的情况下,CSAMT测深法对地下水探测具有非常好的效果。

In order to exploit and utilize groundwater resources,Fan Town area of Taian City has selected CSAMT sounding method for exploration.The exploration target layer is 200 m to shallow,the frequency is 5-9600 Hz,the collection time is 30 min,and three wells are arranged.After drilling and pumping test,the average water output is 30 m^(3)/h.The conclusion shows that CSAMT method has a very good effect on groundwater detection when the depth of high density electrical method is not enough and the efficiency of electric sounding is low.
