The regional deformation anomaly of medium - term phase ( 1 ~ 3 years or more ) before strong earthquake occurrence usually shows three aspects of common characteristics : for regional vertical deformation, it shows distribution features of anomalous uplift area and concentration belt - high gradient belt of vertical differential deformation ( some of them reflect distribution of four quadrants ) related to tectonics ; for horizontal movement, it shows features of centralized high strain area ( or zone ) of domination shear deformation related to active blocks and faults ; it shows common features of regional vertical deformation anomaly area and high strain distribution area of horizontal deformation

    摘要強震前中期階段( 1 ~ 3年或稍長)區域性形變異常往往表現出3個方面的共性特徵:區域垂直運動變形呈現與構造有關的異常隆起區、垂直差異變形高梯度帶(有的還呈「四象限」 )分佈特徵;水準運動變形呈現與活動地塊及斷裂構造有關的、以剪切變形?主的高應變集中區(帶)特徵;區域性垂直形變異常區與水準形變的高應變分佈區共性的特徵。
  3. The choice dam type is especial importance, during the designed research of the rock - fill dam, particular under the rock - fill dam with very deeply cover layer, the stress and strain of the middle wall and cutting interpenetration wall of the dam foundation is mostly sensitive, whether the. design of dam is scientific and reasonable, it is very important for cutting interpenetration and stability of the dam, the article offer the reference for the design of cutting interpenetration in the foundation with deep cover with earth the water conservancy in xiaban zone, based on the study and analysis the design of cutting seep in the foundation with deep cover with earth, cutting interpenetration concrete wall and the joining model of cutting interpenetration material in body of dam and the applying effect in the practical worko based on the foundation which absorbed and summarize the achievement of design and research in the inter and outer country, for the project of the clay vertical middle wall and vertical cutting interpenetration, the asphalt concrete vertical middle wall and vertical cutting interpenetration the clay inclined middle wall and the lever carpet layer cutting interpenetration, respectively in terms of the different stage of complete period sluice period and working condition, adopting nonlinear calculate and analysis with the finite element method ; carrying the analysis and study with the 3d finite element method as to the different joining model of the left bank high slope cutting interpenetration body and the foundation concert cutting interpenetration wall ; carrying the analysis and study with the 3d finite element method as to the effect of the wall stress and strain because of the different elasticity modulus of the concert cutting interpenetration wall through the analysis and study with the different project. have comparatively all - around comprehended the various model dam, particular the distribute rule of stress and strain of the cutting interpenetration system, provide for the important evidence of the plastic area size the join model of the foundation cutting interpenetrate wall and dam body cutting interpenetrate system the choice of the dam model and the design of the structure of the dam body, the result of research and advice have very importance value in design and building for the similarity project

    工程設計中,壩型的選取顯得尤為重要,特別對于壩基有深厚覆蓋層的堆石壩,心墻和壩基防滲墻的應力和變形是壩體、壩基最敏感的部位,設計方案是否安全、科學和合理,對大壩防滲和穩定起到至觀重要的作用。本文研究分析了國內外深厚覆蓋層基礎防滲設計、壩基混凝土防滲墻與壩體防滲體銜接形式及工程實際應用效果,為下坂地水利樞紐工程深厚覆蓋層基礎防滲設計的方案選擇提供了參考;在吸收和歸納了國內外堆石壩的設計研究成果的基礎上,對粘土心墻和壩基垂直防滲方案、瀝青混凝土心墻和壩基垂直防滲方案以及粘土斜心墻和壩基水平鋪蓋防滲方案,分別按竣工期和蓄水運行期的不同工作情況進行了有限元非線性計算分析;對左岸高陡邊坡的大壩防滲體與基礎混凝土防滲墻的不同結合型式進行了三維有限元靜力計算分析和研究;對混凝土防滲墻不同彈性模量對墻體應力和變位的影響進行了三維有限元靜力計算分析和研究。通過對不同方案的計算分析和研究,比較全面的了解了各方案壩體,尤其是防滲體的應力和變形分佈規律,為壩型選擇、壩體結構設計、基礎防滲墻與壩體防滲體的結合型式以及塑性區大小的確定提供了重要依據。
