在岩溶水利水电工程地质勘察中,岩溶水是主要的研究对象之一。其中,水化学分析更是一项必不可少的研究科目。但是在以往的勘察中,水化学分析常常局限于评价水质及其侵蚀性。众所周知,水化学组成乃是水溶液和介质互相作用的结果。岩溶水运动过程主要是水和碳酸盐岩相互作用的一种物理和化学作用过程,在某种程度上也是水溶液运动途程地球化学环境的实际记录。对水利水电工程来讲,和建筑物关系最为密切的岩溶水主要分布在河谷及其岸坡附近地段。不少工程水化学分析实例证明,这些地区的岩溶水无论是其化学组成、离子迁移运动和变化特征都有其一定的规律。近些年来,我们在一些工程中(主要位于强隆峡谷山区),尝试根据岩溶水的某些地球化学特征来分析研究一些比较复杂的水文工程地质问题。现抛砖引玉,提出来和同志们共同讨论。由于篇幅,本文侧重于方法的介绍,具体分析和引证另有专文,恕不赘述。
In karst water conservancy and hydropower engineering geological survey, karst water is one of the main research objects. Among them, water chemical analysis is an essential research subject. However, in previous surveys, hydrochemical analysis was often limited to assessing water quality and its aggressiveness. It is well known that the chemical composition of water is the result of the interaction of aqueous solutions with the medium. The process of karst water movement is mainly a physical and chemical interaction process between water and carbonate rock and to some extent the actual record of the geochemical environment during the movement of water solution. For water conservancy and hydropower projects, the karst water that is most closely related to buildings is mainly distributed in the valley and near the bank. Many engineering examples of hydrochemical analysis show that the karst water in these areas has its own laws regardless of its chemical composition, ion mobility and variation characteristics. In recent years, we have attempted to analyze and study some of the more complex hydrogeological problems based on some geochemical characteristics of karst water in some projects (mainly in the Qianglong gorge area). Are throwing bricks, put forward and comrades to discuss. Due to space, this article focuses on the introduction of the method, the specific analysis and quotation of another article, will not repeat them.
