【摘要】 根据不同化学组分在坝基岩水系统中的相互转化规律,建立了坝基老化的反向水文地球化学模型,利用Barrodale-Roberts算法对模型进行求解,计算给定随机误差极限范围内不同坝基渗漏量条件下的坝基岩土体与地下水溶液间的物质交换量及其变化范围。将该模型应用到新安江大坝右坝段坝基老化分析中,结果表明所建立的模型可靠实用,求解速度较快。更多还原

【Abstract】 Based on the regularity of interconversion of different chemical components in the dam foundation water-rock interaction system,an inverse hydrogeochemical model for simulating dam foundation ageing was established,and the Barrodale-Roberts algorithm was adopted to solve the model.The amount of mass transfer and its range between the rock mass and groundwater of dam foundation within the specified stochastic error limit are obtained under different leakage conditions.The application of the model to dam foundation ageing analysis of the right section of the Xin’anjiang Dam shows that the model is reliable,practical,and fast in calculation.更多还原
