研究坦桑尼亚达累斯萨拉姆区域水文地质资料及文献，浅析含水层分布、补给来源、开采现状，依托坦桑尼亚KINYEREZI燃气电站项目，开展大地电磁测深和电测井等地球物理水文勘探，探究地层水文物理性质，结果表明构成半承压含水层的粉细砂，同样具有较高的粘质含量，渗透性并不十分理想；下伏粘质砂层，局部渗透性相对较好，但仍难以作为可用含水层。建议达市工业大量用水的情况下，尝试沿海灰岩地层取水或直取海水，并进行海水淡化处理。%On the base of researching regional hydrogeology conditions, the distribution of the aquifer, recharge sources, and groundwater exploitation are analyzed. Relying on Tanzania KINYEREZI III Power Plant Project, magneto telluric survey and electrical logging were carried out to study the physical properties of aquifer. The result shows that fine sand which has been seen as half confined aquifer also has high clay content and the permeability is not very satisfactory; Underlying clay—bound sand is not an available aquifer though permeability is relatively good at some depth. It is proposed that industries that have a great need for water can take saline water from coastal limestone or sea and develop water desalination system.
