Examples
- In this project , the maximum height of the dam is 81m , but the deep overburden in the riverbed has the depth of 147 . 95m which is about two times of the maximum height of the dam body , so the seepage and liquefaction prevention of the dam foundation becomes the key and important problem in the design of the dam project . the static stress and deformation under three different projects - horizontal blanket project , clay core project and asphalt core project - for the dam is analyzed comprehensively . the damage that may be induced by variable factors on the dam body in time of engineering completion and water impounding operation period is seriously studied
其次，将这一模型用于分析下坂地水利枢纽工程，由于该工程河床覆盖层深度最深达147 . 95m ，是坝体高度的近两倍左右，坝基的渗流和液化成为坝体安全主要问题，本文对该坝的三种设计方案即水平铺层防渗方案、粘土心墙防渗方案及沥青心墙防渗方案的静态应力位移及坝体在竣工期、蓄水期等各个阶段可能产生的破坏进行了认真研究。 - 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
工程设计中，坝型的选取显得尤为重要，特别对于坝基有深厚覆盖层的堆石坝，心墙和坝基防渗墙的应力和变形是坝体、坝基最敏感的部位，设计方案是否安全、科学和合理，对大坝防渗和稳定起到至观重要的作用。本文研究分析了国内外深厚覆盖层基础防渗设计、坝基混凝土防渗墙与坝体防渗体衔接形式及工程实际应用效果，为下坂地水利枢纽工程深厚覆盖层基础防渗设计的方案选择提供了参考；在吸收和归纳了国内外堆石坝的设计研究成果的基础上，对粘土心墙和坝基垂直防渗方案、沥青混凝土心墙和坝基垂直防渗方案以及粘土斜心墙和坝基水平铺盖防渗方案，分别按竣工期和蓄水运行期的不同工作情况进行了有限元非线性计算分析；对左岸高陡边坡的大坝防渗体与基础混凝土防渗墙的不同结合型式进行了三维有限元静力计算分析和研究；对混凝土防渗墙不同弹性模量对墙体应力和变位的影响进行了三维有限元静力计算分析和研究。通过对不同方案的计算分析和研究，比较全面的了解了各方案坝体，尤其是防渗体的应力和变形分布规律，为坝型选择、坝体结构设计、基础防渗墙与坝体防渗体的结合型式以及塑性区大小的确定提供了重要依据。
