During the finite element modeling of the bridge, the factors affecting the accuracy of the finite element model are discussed in detail, such as, the geometrical non - linearity of the cable including gravitational sag and initial tension, and the structural orthotropic steel box - girder deck to be equivalent to physical orthotropic deck by using compound material mechanics, and so on
在建模過程中，盡可能多地考慮了一些影響全橋有限元模型精度的因素：如斜拉索的幾何非線性（重力垂度和初始應力） ，將構造正交各向異性鋼箱梁橋面板用復合材料力學的方法等效為物理正交各向異性板等。 -
The paper use drucker - prager model as the constitutive model of soil, use pole module as the model of soil nails, use girder module as the model of soil - cement mixing piles, use goodman module as the model of interface, an iterative - increment method is used to solve nonlinear equation. 2. the paper has a further research on the influence of compound soil nailing behavior in the perspective and the axial strength of the soil nails of the effect of the stiffness of soil, the stiffness of soil - cement mixing piles, the width of soil - cement mixing piles, the length of nails, the angle of nails
本文根據目前復合型土釘墻支護的研究現狀和工程實際需要，採用有限單元法對攪拌樁-土釘復合型土釘墻的力學特性進行數值分析，本文的主要工作內容有以下幾個部分: 1 .利用同濟曙光有限元軟體（ geofba ）對攪拌樁-土釘復合型土釘墻支護進行了非線性有限元分析，在有限元計算中，本文採用了drucker - prager模型作為土體的本構模型，土釘採用了桿單元模型，攪拌樁和噴射混凝土面層的組合體採用了梁單元模型，接觸面單元採用了goodman單元模型，非線性求解方法為增量迭代法。
