地下水管理模型中的参数随机性问题

Parameter stochastic problems in groundwater management model

通过一假设的水文地质管理问题 ,建立了该问题的机会约束随机管理模型 ,利用Taylor展开法分别就渗透系数、弹性给水度、初始流场和边界水位的随机性对管理结果的影响进行了计算分析 ,得出了渗透系数和一类边界条件的随机性对管理结果的影响最明显 ,而弹性给水度的随机性对管理结果的影响很小 ,初始水位只影响疏干时间而对最终的稳定疏干水量没有影响等一般规律 ,并给出了理论分析 .

A hydrogeological chance constrained management model is constructed for hypothetical hydrogeolgy problem. The affections of permeability, storage, initial condition and boundary condition on the management results are calculated by Taylor series method. The general relationship between the parameter stochastic property and management results is gotten, it is that the effect of stochastic for affections of permeability and the first boundary condition on management results is obvious, and the effect of stochastic of storage on the management results is very small, and so on.
