摘要
在地下水渗流理论的基础上,建立了潜水非稳定井流计算的变边界渗流模型.针对潜水非稳定井流问题边界的可变性,运用拉普拉斯变换,给出变边界渗流模型的初步解析解.为了便于实际应用,提出了追踪变边界计算割离井法,编制了FORTRAN计算程序.
Based on underground water seepage theory,the variable boundary seepage model of the unstable well flow in underground water flow is established.The analytic solution of the model is obtained applying Laplace Transformation.For the sake of the convenience of practical application,an isolated well numerical calculating method for tracing the variable boundary is put forward and FORTRAN program is complied for the method.
