【摘要】：近年來隨著世界水電事業(yè)的飛速發(fā)展,水利工程的建設投資越來越高,工程規(guī)模十分巨大,修建的水工建筑物朝著“高、大”的方向發(fā)展。隨著水利工程所面臨的技術(shù)性難題越來越突出,工程安全問題也日益顯著,大壩安全監(jiān)測作為保障大壩安全運行的重要手段,具有重要意義。本文通過對溪洛渡大壩壩基滲流資料的分析,預測大壩壩基的滲壓情況以及發(fā)展趨勢,為大壩的安全運行提供依據(jù)。具體工作內(nèi)容包括:(1)通過分析溪洛渡拱壩河床壩段和岸坡壩段滲壓計的監(jiān)測資料,并計算帷幕后滲壓系數(shù),監(jiān)測資料分析成果表明:壩基滲壓系數(shù)均小于溪洛渡拱壩設計值,表明溪洛渡水電站拱壩壩基帷幕防滲效果良好。(2)根據(jù)成因分析,將壩基滲壓分解為水位分量、溫度分量和時效分量,分別采用逐步回歸與偏最小二乘回歸方法建立壩基滲壓監(jiān)控模型,統(tǒng)計模型分析結(jié)果表明:兩種方法建立的監(jiān)控模型擬合效果均較好,符合壩基滲壓變化規(guī)律的一般認識。監(jiān)控模型顯示水位分量占主導地位,而隨著大壩由初蓄期進入運行期,時效分量逐漸減小。(3)溪洛渡安全監(jiān)測資料管理及分析云服務軟件系統(tǒng)(簡稱為安全監(jiān)測系統(tǒng))主要用途包括數(shù)據(jù)管理、資料分析、系統(tǒng)管理等。本文詳細介紹了監(jiān)測系統(tǒng)的使用說明,并將壩基滲壓統(tǒng)計模型嵌入到大壩安全監(jiān)測系統(tǒng)中,便于實時監(jiān)控并及時預測壩基滲壓的變化趨勢。
[Abstract]:In recent years, with the rapid development of hydropower industry in the world, the construction investment of water conservancy project is more and more high, the project scale is very large, and the hydraulic structure is developing in the direction of "high and large". As the technical problems faced by water conservancy projects become more and more prominent, the problems of engineering safety are becoming more and more prominent. As an important means to ensure the safe operation of dams, dam safety monitoring is of great significance. Based on the analysis of seepage data of Xiluodu dam foundation, the seepage pressure of dam foundation and its development trend are predicted in this paper, which provides the basis for the safe operation of the dam. The main contents are as follows: (1) by analyzing the monitoring data of the seepage gauge in the river bed and bank slope of Xiluodu arch dam, and calculating the seepage coefficient behind the curtain, the results show that the seepage pressure coefficient of the dam foundation is smaller than the design value of the Xiluodu arch dam. The results show that the curtain of the arch dam foundation of Xiluodu Hydropower Station has a good anti-seepage effect. (2) according to the cause analysis, the seepage pressure of the dam foundation is decomposed into water level component, temperature component and aging component. Stepwise regression and partial least square regression are used to establish the monitoring model of seepage pressure of dam foundation. The results of statistical model analysis show that the two methods have good fitting effect and accord with the general understanding of the law of seepage pressure change of dam foundation. The monitoring model shows that the water level component is dominant, and as the dam moves from the initial storage period to the operational stage, (3) data management and analysis of security monitoring data in Xiluodu (referred to as security monitoring system) are mainly used in data management, data analysis, system management, etc. This paper introduces the usage of the monitoring system in detail, and embeds the statistical model of seepage pressure of dam foundation into the dam safety monitoring system, which is convenient for real-time monitoring and timely predicting the changing trend of seepage pressure of dam foundation.
