水-岩化学平衡模拟中误差传递及灵敏度分析

水\|岩化学平衡模拟中误差传递及灵敏度分析 ①

以水岩化学平衡模型ＷＡＴＥＱ４Ｆ为基础程序，选取平顶山矿区一典型岩溶水水点，对固定温度和变化温度两种情况下，水岩化学平衡模拟中输入的水化学分析数据误差传递进行了研究。结果表明，水化学分析数据误差能够强烈地影响水岩化学平衡模拟结果；不同的水化学变量（误差）对不同的矿物的饱和指数的影响程度不同；在许多情况下。

With the water\|rock chemical equilibrium model WATEQ4F as the basic program and with a typical karstic water point in Pingdingshan mining area selected,the error transmission of the hydrochemical analysis data input in the water\|rock chemical equilibrium simulation was studied.Results show that the error in the hydrochemical analysis data can strongly effect the results of the water\|rock chemical equilibrium simulation,and different hydrochemical variables(errors)affect differentaly the saturation indices of different minerals.In many circumstances,the error of saturation indices of minerals varies with the variation of temperature.
