【摘要】 水文地质参数是地下水资源评价及合理开发利用的基础,是水文地质工作的难点。基于双辽市2001～2016年的降水、蒸发及地下水埋深数据求解水文地质参数中的水位变动带给水度、蒸发极限埋深、蒸发系数、降水入渗补给系数。即采用阿维里扬诺夫等公式建立矛盾方程组,利用线性规划法求解水位变动带给水度和潜水蒸发极限,之后求解降水入渗补给系数和潜水蒸发系数。对比非线性规划算法求解结果,同时利用神经网络法预测参数变化范围,将所求结果与历年资料进行对比,确定参数结果的可信度。该计算结果不仅给双辽市地下水资源评价提供了科学依据,同时也为水文地质参数确定提供了一种准确可行的方法。更多还原

【Abstract】 Hydrogeological parameters are the basis of groundwater resources evaluation and rational exploitation and utilization,and are the difficulty of hydrogeological work.Based on the precipitation,evaporation and groundwater burial depth data of Shuangliao City from 2001 to 2016,the specific yield,evaporation limit depth,evaporation coefficient and precipitation recharge in hydrogeological parameters were calculated.That is to establish the contradictory equations by using the formula of C.Q.ABepbxhob,and the specific yield and the limit of submerged evaporation in the water level fluctuation zone were solved by using linear programming method.And then the recharge coefficient of precipitation infiltration and the coefficient of submerged evaporation were obtained.Compared with the results of nonlinear programming algorithm,the neural network method was used to predict the range of parameters variation.The reliability of the results was determined by comparing the results with the historical data.The results not only provide a scientific basis for evaluation of groundwater resources in Shuangliao City,but also provide an accurate and feasible method for determination of hydrogeological parameters.更多还原
