Abstract
It took Shuanghe Hydropower Station as the research background,considering the deep cover layer and the ancient located body founda-tion problems. By using nonlinear D-P constitutive model,with the ANSYS three-dimensional finite element software,it had proven the typical con-ditions of three-dimensional stress field and displacement field,analyzed the stability of the structure,revealed stress distribution of sluice founda-tion and deformation law of the sluice chamber,evaluated the effectiveness of sluice impervious curtain measures. It obtains from the calculation that in four kinds of conditions of deformation and stress laws are consistent. Finished built deformation and stress level are the largest,followed by normal water level conditions. The final in turn is checking flood operating conditions and design flood conditions. Sluice dam deformation and de-formation difference between the monoliths are both small and agreement with the actual monitoring data. Under various conditions to the maximum normal stress and principal stress are small,and most of the sluice base are compressive stress. The maximum compressive stress is less than the foundation allowed bearing capacity. Gate chamber structural deformation and stress meet the design requirements.关键词
