摘　　要：为了研究地下水模拟时,水文地质结构对其的影响,通过建立随机模型来对地下水进行随机模拟。建立更加符合实际情况的随机水位地址参数场,并将其带入到有限元软件中,模拟得出随机结果。通过对比分析确定模型和随机模型的水位变化拟合图与末流场拟合图,结果表明地下水模拟时,随机模型和确定模型的变化趋势大致相同,拟合效果与实测场相比都表现良好,但随机模型与确定模型相比,可能性更多,在细节上的处理也较为精确,与实测流场拟合较接近。In order to study the effect of hydrogeological structures on groundwater simulation,stochastic simulation of groundwater is performed by establishing a stochastic model.A more realistic stochastic water level address parameter field was established and brought into the finite element software to simulate the stochastic results.By comparing and analyzing the fitted plots of water level change and end-flow field of the deterministic and stochastic models,the results show that the change trends of the stochastic and deterministic models are approximately the same when groundwater is simulated,and the fitting effects both perform well compared with the measured field,but the stochastic model has more possibilities and is more accurate in details compared with the deterministic model,and is closer to the measured flow field fitting.
