Stability of rock slopes is generally controlled by the structure of rock masses, especially the soft structure surfaces. analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes. the weak structure surfaces are mainly bedding planes, faults, joints, schistosity plane and contact zones of intrusive bodies. since they are different in genesis and scale, the rock masses are different in features and mechanical intensities. based on the combination of rock structure bodies, 15 basic modes of deformation and failure of rock slope are systematically summarized. the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies. there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project
巖體結構,特別是軟弱結構面對基巖斜坡變形與破壞具有顯著的控製作用,巖體結構模式分析是建立斜坡地質模型和數學模型的關鍵和評價斜坡穩定性的基礎。巖層層面斷裂構造節理裂隙片理與劈理以及侵入體和圍巖的接觸帶等是控制基巖斜坡穩定的軟弱結構面,這些成因不同大小不一的結構面將巖體分割成性質各異力學強度不均的各種巖體結構體,構成了15種基巖斜坡變形破壞的巖體結構基本模式。不同結構體的重新組合與排列是斜坡失穩的內在原因。Contact metamorphic action

青金石是由接觸交代變質作用形成,主要賦存於硅酸鹽-鎂質矽卡巖中和鈣質矽卡巖中。Because of the different material property of the piles and soil, shear stress is produced on the contact surface between piles and soil, which may cause slide and crazing of the soil mass under workload. in order to reflect the mechanical character precisely on the contact surface, a new kind of element, plane - plane contact element is introduced. the principle of the process is presented in detail and the finite element model is established with the consideration of the soil ' s elastoplastic constitutive relation
由於樁體結構的材料性能與周圍土層性質相差較大,在荷載作用下有可能在其接觸面上產生較大的剪應力從而導致錯動或開裂,為了充分反映樁土接觸面上的受力及變形特徵,考慮樁土之間的共同作用,在樁土接觸面處設置面面接觸單元,將採用接觸單元和不採用接觸單元兩種演算法的計算結果與模型試驗結果進行比較,驗證了本文接觸界面處理的合理性。Mainly thinking over ore - bearing rock series and giving consideration to ore - forming process, the author divides the gold deposits in fujian into four categories which include metamorphic rock category, volcanic rock category, sedimentary clastic rock category and igneous rock intrusive contact category
採用以容礦巖系為主體兼顧成礦環境和成礦作用的分類原則,把福建省金礦劃分為變質巖型、火山巖型、沉積碎屑巖型和侵入巖內外接觸帶型四類。And relying on this, our laboratory proposes a new cladding method. by means of large dynamic explicit fem code ansys / ls - dyna, the numerical simulation was carried out in bimetal forming process. during the simulation of the forming process, the large deformation of the strip should be considered, as well as geometrical and material nonlinear, the contact between the roller and the strip, the contact between two metal sheets and the load. as for these problems, we can use node to surface contact and relative parameters, biso model is introduced, the load is applied as array
