调查水文地质条件,建立相应的数学模型是地下水资源评价的重要步骤。当水文地质条件研究程度低时,一般采用随机模型;当比较全面、确切地掌握水文地质条件时,则采用确定型。而后者需要计算含水层的水文地质参数。下面根据国内外资料介绍几种裂隙含水层参数的计算方法。一、风化裂隙潜水含水层渗透系数计算根据岩心观察,浅层基岩风化裂隙发育程度随埋深减弱,富水程度和导水性相应逐
Investigation of hydrogeological conditions, the establishment of the corresponding mathematical model is an important step in groundwater resources assessment. When the degree of research on hydrogeological conditions is low, a stochastic model is generally adopted. When the hydrogeological conditions are comprehensively and accurately grasped, a deterministic model is adopted. The latter needs to calculate the hydrogeological parameters of the aquifer. The following based on domestic and foreign information on several kinds of fractured aquifer parameters calculation method. I. Calculation of permeability coefficient of weathered fractured submerged aquifer According to the observation of the core, the degree of development of the weathered fractures of shallow bedrock decreases with the depth of burial,
