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 design and construction method to a new - typed cofferdam is introduced. after its project application, such advantages are proved as less investment, high construction pace, less labour power and dredging river
