Through field investigation and analysis indoor , with studying all hydrochemistry data in detail , including macro components and micro components , the author finds out the hydrochemistry feature of ground water . for further specifying the ground water system , with cluster analysis of macro components of surface water and ground water in total 147 samples and the analysis of micro components , including ree , the main ground water systems are distinguished by and large , especially the ground water system main of fault no . 7 and fault no . 15 water bearing belts which have differences at macro and micro components between the two ground water systems , moreover , the main hydrogeochemistry effects are established such as lixiviation , oxidization , precipitation and mixing effect , especially the mixing effect which result in the complexit y of the hydrochemistry of deep bearing tectonic fracture water . based on them , the hydro geological model of upper dam base is established , meanwhile the author summarizes the hydrochemistry feature of weathering crevice water , surface tectonic crevice water and deep tectonic crevice water 为此，本文以大岗山坝区水文地球化学问题为研究对象，通过野外调查和室内分析，详细的研究了坝区水化学资料，包括宏量组分、微量组分，查明了坝区地下水水化学特征，对采集的147个地表及地下水样的宏量组分进行聚类分析，结合微量元素，稀土元素的研究，并应用二氧化硅地热温标确定了深部构造裂隙水的热源深度，基本区分了坝区各个主要地下水水系，特别是以f7 、 f15断裂含水带为主的地下水系，它们的宏量组分、微量组分以及稀土等方面均存在差异，以此为基础，结合坝区水文地质条件，建立了坝区的上坝址的水文地质模型，同时通过分析了坝区花岗岩区的水化学资料，确立了坝区主要的水文地球化学作用，分别为：溶滤作用、氧化作用、沉淀作用、以及混合作用，混合作用是导致深部承压裂隙水水化学复杂的主要原因，并总结了坝区风化裂隙水、浅部构造裂隙水、深部构造裂隙水的水化学特征。
