摘要
针对解析方法求解半无限含水层井流问题,对直线补给边界附近的井流采用数值方法进行模拟计算,并将两种方法进行比较,数值计算结果表明,存在补给边界时,抽水一定时间以后降深能达到稳定,但仅仅代表观测点处降深达到稳定,而整个渗流场并未达到稳定状态。
Well flow in semi-infinite aquifer is calculated with analytical method, the well flow near the linear recharge boundary is modeled with numerical method. To compare to the results of two methods, The result of the numerical method shows, when existing the recharge boundary, after pumped some time the fall of water level can reach nearly steady, but the steady state is only in the observation point, and the whole seepage field doesn＇t reach steady.
