摘要
本文介绍了用有限单元法在天堂河流域进行浅层地下水可开采量预测工作的过程、成果以及对今后工作的建议。从文中可以看出,用有限单元法预测地下水流问题,具有适应能力强、计算速度快、利于多方案比较等优点。尤其对潜水的非线性问题处理,能够达到足够高的精度。
The process and results of, and tht suggestions for forecasting the d ischarge of wells by finite element method s in shallow uncon- fined aguifer in Tiantang river valley are discribed in this paper Obviously,to use finite element methods for forecasting ground water flow has many advantages, the adaptability is better, the calculating speed is higher, etc.. Especially, when it is used to solve nonlinear problems in unconfined aquifer, the precision of ca- lculation is quite good.
