随着沙湾县安集海镇经济社会的进一步发展,为提高本项目区供水保证率,本次利用安集海镇已有的水井和地质勘察资料等工作成果,综合研究安集海镇水源地地下水含水层结构及富水性,得到项目区含水层富水性分布。结果表明:南洼地第四系砂砾石层厚度400~600 m(中上更新统250~350 m,下更新统150~250 m);岩性为砂砾石地层,渗透系数相对较大,机井抽水影响半径多为200~400 m,地下水埋深大于60m,区内地下水补给条件好且具有较大的存储空间,地下水埋深虽较大,但对本次饮水安全工程来说仍是建设水源地较好的地带。
With the further economic and social development of Anjihai Town in Shawan County, in order to improve the water supply guarantee rate in this project area, this time, using the existing wells and geological survey data in Anjihai Town, this paper comprehensively studied the water resources of Anjihai Town Groundwater aquifer structure and water-rich, aquifer water-rich distribution of the project area. The results show that the thickness of Quaternary gravel layer in the southern depression is 400 ~ 600 m (middle and upper Pleistocene 250 ~ 350 m, lower Pleistocene 150 ~ 250 m); lithology is gravel stratum, the permeability coefficient is relatively large, The influence radius is mostly 200-400 m, and the groundwater depth is more than 60m. The groundwater recharge in the area is good and has a large storage space. Although the groundwater depth is large, it is still a water source for the drinking water safety project Better zone.
