論述了三峽大江截流及二期圍堰實施過程中的施工進度計劃、料場規劃與土石方平衡、截流方式與圍堰斷面形式、截流進占程序和時段、防滲形式、防滲墻施工等主要技術問題的優化完善過程I have already observ d how i brought all my goods into this pale, and into the cave which i had made behind me : but i must observe too, that at first this was a confus d heap of goods, which as they lay in no order, so they took up all my place, i had no room to turn my self ; so i set my self to enlarge my cave and works farther into the earth, for it was a loose sandy rock, which yielded easily to the labour i bestow d on it ; and so when i found i was pretty safe as to beasts of prey, i work d side - ways to the right hand into the rock, and then turning to the right again, work d quite out and made me a door to come out, on the out - side of my ale or fortification
現在我必須補充說一下，就是那些東西起初都雜亂無章地堆在那裡，以致占滿了住所，弄得我連轉身的餘地都沒有。於是我開始擴大和挖深山洞。好在巖石質地是一種很松的沙石，很容易挖，當我覺得圍墻已加固得足以防禦猛獸的襲擊時，我便向巖壁右邊挖去，然後再轉向右面，直至把巖壁挖穿，通到圍墻外面，做成了一個可供出入的門。By drilling to weak position, the jet - grouting technique breaks through and mixes with soil and stone of dam foundation to form diaphragm - wall
高壓噴射灌漿可由鉆機鉆孔至需處理的薄弱部位，通過高壓射流的沖擊攪拌，水泥漿在噴射范圍內與地層土石顆粒摻混攪合后形成防滲墻。This paper analyzes and explores stress strain model and principle of the project of concrete diaphragm wall after concluding other engineers and project practices and describing the seepage and deformation character of the plastic concrete used in the cofferdam of the second stage of the three gorges project. we analyze and forecast the change trend by using mathematics statistics regression, then we get the best regression equation. finished it, we used this way to the cofferdam of the second stage of the three gorges project. it proves that the method which i have introduce in this article is effective for the stability of concrete diaphragm wall and it is also a valid for supervising cofferdam security after using it in many projects
本文在總結前人和其他工程實踐的基礎上，結合三峽二期土石圍堰實例綜合分析塑性混凝土防滲墻的滲透和變形特性，對三峽二期圍堰砼防滲墻的應力應變模型、原理進行了分析、探討，在監測分析資料的基礎上進行數學統計回歸分析，並對變形進行預測，通過對砼防滲墻及堰體的應力應變監測數據進行數學統計回歸分析，得出了最佳回歸方程，並對三峽二期圍堰變形進行預測，達到了對圍堰安全性監測評價的最佳效果。Abstract : a brief introduction to scientific research in the three gorges project ( tgp ) and the applications of research achievements is given, which include treatment of newly slited layer on the foundation of the first stage earth - rock cofferdam, dumping bottom technique of river closure in deep water, construction of cut - off walls in the second stage earth - rock cofferdams, 3 - d computer simulation of river closure, concrete casting alternatives and selection of major construction equipment for the second stage construction optimization of durability of raw materials of concrete, deep sliding resistance and stability of the intake dam section, the section of the intake of the power station, the intake penstock of the power station, layout and hydraulics problems of shiplocks, stability of high slopes of shiplocks, and optimization of the system structural anchor bars to reduce the risk of cracking in the concrete wall and 700mw turbine generator units
