摘要:
将蒙特卡罗方法与数值解法相结合，通过模型反演得到了115组模拟水位与观测水位的残差平方和低于10的渗透系数场。通过蒙特卡罗方法统计，基岩含水层渗透系数均值的取值范围在26.4～27.8 m/d之间，相应的置信度为0.95的置信区间在25.0～30.0 m/d之间。水源地内F7断层附近含水层的渗透系数最大，向两侧渗透系数逐渐减小，并且水源地西部含水层的渗透系数大于东部含水层的渗透系数。
Abstract:
Monte Carlo method was a method which computed approximate solutions by stochastic statistics tests and simulations and modernized by computer simulation researches. This paper combined Monte Carlo method and numerical method，gained 115 hydraulic conductivity distributions which sums of squares for error between simulated groundwater level and observed groundwater level were lower than 10 by model inversion. Statistics of hydraulic conductivity distributions was carried out later，results showed that means of bedrock aquifer s hydraulic conductivity in the source were 26.4～27.8 m/d and corresponding 95% confidence intervals were 25.0～30.0 m/d. In the source，the aquifer near F7 fault had the largest hydraulic conductivity and gradually reduced to west and east sides and hydraulic conductivity in the west aquifer was larger than the aquifer in the east.
