摘要
在水文地质测绘、勘探、现场试验和TEM地球物理勘探等工作基础上,建立三维含水结构模型,通过数值模拟方法对水源地开发规模进行比选分析。通过3个不同提水方案比选,结果表明:每年1 000×10~4m^3的地下水开采量所形成的地下水位最大降深位为9.67m,水位恢复后地下水位降深介于1～1.5m(地下水埋深3～5m),对减少蒸发、降低土壤盐渍化作用显著。长期预测模型显示:在工程实施的第三年,地下水位控制在临界深度附近并保持稳定。经方案比选后新疆沙雅县新垦农场水源地地下水开采量确定为1 000×10~4m^3/a,可以满足春灌及控制地下水位到临界深度的需要。
Based on the work of hydrogeologic survey, exploration, pumping test and geophysical exploration (TEM), the three-dimensional structure which contained the groundwater was put up in this paper. And through the three-dimensional finite difference simulation of groundwater, this paper also discussed the exploit quantity of the groundwater of XINKEN Farmland of XINJIANG province by two principles: firstly, exploration must meet with the shortage of the local agriculture and industry for one big reservoir which...
