The building of water-conservancy and water-electricity projects has remodeled a new environment, the second environment, in karst areas. It has changed or adjusted a series of cyclic conditions, such as "stable" geomorphy, climate, ecology, karst hydrogeology, engineering geology, natural stress and pollution. In this whole process of comp Heated remodeling and reforming,the good cyclic effect is prevailing over the bad one all the time, and new cyclic conditions are to be finally "stabilized" .

喀斯特区水利水电工程的兴建再塑了新环境(第二环境)。它改变或调整了“稳定”的地貌、气候、生态、喀斯特水文地质、工程地质、自然应力、污染等一系列条件。在这个复杂的再塑与改造的全过程中,良性循环始终战胜着恶性循环的效应,最后趋于新的“稳定”。

Karst leakage is one of the complicated technical problems in water conservancy and hydroelectric projects.It is mainly related to groundwater table in karstified formations and distribution of karat caves. The problem cannot be solved effectively only by qualitative analysis depending on visual observation and empirical analysis.

Karst leakage is one of the complicated technical problems in water conservancy and hydroelectric projects.It is mainly related to groundwater table in karstified formations and distribution of karat caves. The problem cannot be solved effectively only by qualitative analysis depending on visual observation and empirical analysis. The trend surface analysis has led to an approach to interprete the essence of the problem on the basis of large amounts of observation data available. The Dahua hydropower station and the Geheyan dam site is taken as an example in the discussion on application of multinomial trend surface equation. The existence of a groundwater divide is thus proved and the cause of no karst leakage is elucidated against the geological setting with subterranean streams distributed in Liangshan segment in the Dahua hydropower station area. Trend surface analysis is also done for the different karst development on the river bed at the Gehe Rock dam site and relevant anomalies are located.

岩溶渗漏是水利水电工程中较为复杂的技术难题之一。而岩溶渗漏又主要与岩溶地下水位及溶洞分布等有关。但是,仅用直观的、经验性的定性描述,已不能有效的解决上述问题。如何从大量的观测资料中分析问题,找出规律,从而更深刻地阐明问题的本质。找出规律,趋势面分析提供了一条分析方法的途径。本文以大化电站和隔河岩坝址为实例,探讨了多项式趋势面方程的具体应用,论证了大化电站亮山地段地下河的分布及地下分水岭的存在,解释了未产生岩溶渗漏的原因。对隔河岩坝址河床岩溶发育的差异性作了趋势分析并圈出了异常点。

Sandwiches occuring in magatite and sedimentary or metamorphic rocks can be divied into two main types i.e. original and secondary according to their geogeneses. This paper places emphasis on the study of argillization of the secondary one. Analysis of the data from three dam sites in South China, shows that the argillization of the sandwiches results from the hydrogeochemical action between rocks and the water in them. In this process, diffluent salt and indiffluent salt are migrated out of the sandwiches in...

Sandwiches occuring in magatite and sedimentary or metamorphic rocks can be divied into two main types i.e. original and secondary according to their geogeneses. This paper places emphasis on the study of argillization of the secondary one. Analysis of the data from three dam sites in South China, shows that the argillization of the sandwiches results from the hydrogeochemical action between rocks and the water in them. In this process, diffluent salt and indiffluent salt are migrated out of the sandwiches in order, as a result, the sandwiches containing diffluent salt or calcareous cement are most easily argillizated.

软弱夹层泥化是水利水电工程建设中经常遇到的工程地质问题,以往的论述多偏重构造成因,本文以三个工程实例的资料,研究了地下水作用下软弱夹层泥化的机理.结果丧明:在水岩系列间水文地球化学作用过程中,易溶和难溶的物质依次被迁移,因而那些含易溶盐的或钙质胶结的粘土岩最易形成泥化夹层;环境变迁加速或推迟了泥化作用的进程;泥化层中粘土矿物成分和特征反映了地下水迳流条件和水岩间相互作用的时间尺度.
