高噴灌漿技術對壩體的原結構影響較小，施工較簡單，工程造價相對較低，對病險壩防滲加固具有較明顯的優越性。 -
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。 -
According to the documentation collected from domestic and abroad wang wei dong who works in huadong architect and structure institute utilizes the similar work property between the underground continuous wall and pile subjected the vertical loads, and introduces poulos method of elasticity and plastic which applies to pile foundation into the calculation for subsidence of underground continuous wall. pujialiu and yu yuzhou from water and electronic engineering of qinghua university, according to the result of three axes, define the concrete parameter utilize the model of non - linear e - b combined with the design cross section of dam in xiaolangdi, yellow river accept the total stress programme of thepd dam, and we analyze the stress and displacement of plastic concrete diaphragm wall by finite element method in comparison with the result of common concrete one. at same time, we consider the effect of the character of plastic concrete diaphragm wall which is composed of different gradients and adopting the level of stress and pulling stress infers whether the plastic concrete diaphragm wall is safe or not
地下連續墻是一種歷史較短的施工方法，目前，砼防滲墻的設計還是以傳統的設計方法為主，根據查找國內外文獻資料，華東建築設計院王衛東利用地下連續墻與樁在豎向荷載作用下的工作性能有相似性，將適用於樁基的poulos彈性理論引入對地下連續墻的沉降計算中；清華大學水利水電工程系濮家騮、于玉貞根據三軸試驗結果確定混凝土的參數，利用非線性e - b模型，結合黃河小浪底土石壩設計剖面，採用thepd土石壩總應力程序，對深覆蓋層塑性混凝土防滲墻的應力、位移進行有限元分析，並與普通混凝土防滲墻計算結果加以對比，同時分析了不同配比塑性混凝土特性的影響，並採用應力水平和拉應力數值來判斷塑性混凝土防滲墻的安全程度。 -
