Application of Orthogonal Experiment on Parameter Sensitivity Analysis of Groundwater Simulation
英文摘要
In the establishment process of groundwater numerical model,due to lack of hydrogeological data,it may lead to the uncertainty of hydrogeological conceptual model and the uncertainty of mathematical model. The analysis of parameters′ reliability is necessary. The orthogonal experiment method has high efficiency and can overcome the defects of other analysis of the parameters sensitivity methods. This paper took Chaoyang District of Beijing as the study area. Range analysis method and variance analysis method were used to analyze the parameters sensitivity. Three parameters of permeability coefficient,specific yield and water storage rate were chosen as sensitivity parameters which closely link to groundwater flow field. The two methods both show that the sensitivity value of permeability coefficient is the maximum parameter,and the water storage rate is the minimal parameter. In the model,the accuracy values of permeability coefficient should be acquired,so as to improve the precision of the model.
