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" .

喀斯特區(qū)水利水電工程的興建再塑了新環(huán)境(第二環(huán)境)。它改變或調整了“穩(wěn)定”的地貌、氣候、生態(tài)、喀斯特水文地質、工程地質、自然應力、污染等一系列條件。在這個復雜的再塑與改造的全過程中,良性循環(huán)始終戰(zhàn)勝著惡性循環(huán)的效應,最后趨于新的“穩(wěn)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.

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.

巖溶滲漏是水利水電工程中較為復雜的技術難題之一。而巖溶滲漏又主要與巖溶地下水位及溶洞分布等有關。但是,僅用直觀的、經(jīng)驗性的定性描述,已不能有效的解決上述問題。如何從大量的觀測資料中分析問題,找出規(guī)律,從而更深刻地闡明問題的本質。找出規(guī)律,趨勢面分析提供了一條分析方法的途徑。本文以大化電站和隔河巖壩址為實例,探討了多項式趨勢面方程的具體應用,論證了大化電站亮山地段地下河的分布及地下分水嶺的存在,解釋了未產(chǎn)生巖溶滲漏的原因。對隔河巖壩址河床巖溶發(fā)育的差異性作了趨勢分析并圈出了異常點。

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.

軟弱夾層泥化是水利水電工程建設中經(jīng)常遇到的工程地質問題,以往的論述多偏重構造成因,本文以三個工程實例的資料,研究了地下水作用下軟弱夾層泥化的機理.結果喪明:在水巖系列間水文地球化學作用過程中,易溶和難溶的物質依次被遷移,因而那些含易溶鹽的或鈣質膠結的粘土巖最易形成泥化夾層;環(huán)境變遷加速或推遲了泥化作用的進程;泥化層中粘土礦物成分和特征反映了地下水逕流條件和水巖間相互作用的時間尺度.
