摘  要:
峄城东郊水源地具有典型的双层结构,上层为第四系粘性土,下层为奥陶系马家沟组石灰岩,石灰岩富水性较好,地下水主要接受大气降水的补给,由于受峄城断裂、吴林断裂、泥沟断裂的共同作用以及第四系覆盖层和水动力、补给条件等的制约,石灰岩单位涌水量一般大于100 m3/(d.m)。利用建立的地下水数学模型,采用2个观测井的水位进行拟合,通过模拟计算2个观测孔的水位,均与实测水位拟合较好,按6口开采井抽水量进行模拟计算,峄城东郊水源地地下水可采资源量为2.0×104m3/d,开采区内水位降深最大20 m。

摘  要:
The water resource field has a typical double-layer structure in eastern suburb of Yicheng,the upper is Quaternary clay,and the lower level is the Ordovician system Machiakou group limestone,limestone has large water yield capaeity.Groundwater mainly accepts the supplies of mospheric precipitation.Because of combined action of Yicheng fraction,Wulin fraction and mud ditch fraction as well as constrains of the fourth system cover layer,water force,supplies condition and so on,limestone unit discharge is generally more than 100 m3/(d·m).Using the established mathematical model of ground water,fitting the water level of two observation wells,through the analog computation,two observation hole′s water level is fitted well with the measured water level.According to analog computation of six exploration wells pumping,the recoverable resource of groundwater in field of water resource in eastern suburb of Yicheng is 2.0 × 104 m3/d,the biggest fall depth of water level is 20 m in the minning area.
