1)drawdown[英]['dr?:daun][美]['dr?,da?n]水位降深
1.A formula for emendation of drawdown in pumping wells for analysis of 2-D finite difference method with rectangular grid or unstructured polygon grid is proposed by introducing the approximate analytical solutions of unsteady well flow suggested by Theis.采用该公式分别对小尺度模型和大尺度模型进行分析,计算结果表明,常规数值法得到的井中水位降深明显偏小,甚至只有实际井中水位降深的1/3~1/4,而经本文公式校正后得到的井中水位则与实际水位接近,相对误差较小,具有较高精度。
2.The developed visualization program is able to illustrate the subsidence magnitude, drawdown and water table variation through charts, t.本论文的研究目的是用计算机可视化研究方法分析地面沉降的发展过程,通过探讨抽取地下水引起地面沉降的机理,基于有限元计算软件模拟地面沉降发展的过程,用图表、动画形式实时反映在抽取地下水作用下整个研究区域内沉降量以及各抽水承压含水层的水位降深、水位变化情况。
