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。 -
Based on the experiment, the influences of tool normal rake, chip pulling angle and chip pulling force on the shape and metallurgical structure of the fiber cross section are studied
通過試驗研究了刀具法向前角、拉屑力和拉屑角等對纖維橫截面形狀和金相組織的影響。 -
The calculation method of the utmost load of gray cast iron beam with rectangle section is obtained through the analysis of limit load behavior of the beam under the united action of bending and pulling, therefore the design method of limit load about forcing parts of cast iron pressure vessels is determined
通過分析灰口鑄鐵矩形截面梁在純彎曲和拉彎組合作用下極限載荷行為，提出灰口鑄鐵矩形截面梁極限載荷的計算方法，由此確定灰口鑄鐵壓力容器受壓元件的極限設計方法。 -
The distance from figure center of the parabola to the potential slide surface is less than half of the section length. mechanical conditions of this method include not only force equilibrium but also moment equilibrium. as for the beam - on - foundation, its pressure can be calculated by homogeneous hypothesis or winkler foundation hypothesis or infinite half elastic foundation hypothesis on the pulling anchor - cable step and by coulomb active earth pressure theory approximatively on the long term working step
對于樁在滑面以上段所受的坡體荷載，提出可按形心偏下的拋物線型分佈模式計算，並在滿足力的平衡條件的同時還滿足力矩平衡條件；對于地樑上作用的坡體荷載，提出在錨索張拉階段可按均布或溫克爾（ winkler ）地基假定或彈性半無限體地基假定來計算，在工作階段則一般可以近似按庫侖主動土壓力理論計算。 -
Abstract : the forming mechanism of the cross section of unbroken metal fibers manufactured by the combined cutting of big inclination cutting and chip pulling cutting is analyzed
文摘:分析了採用大刃傾角-拉屑復合切削方法製造連續型金屬長纖維時纖維橫截面的形成機理。
