研究坝体变位大小和坝体变形的范围，比较其它工程及国际工程经验，探索碾压混凝土重力拱坝坝体变位控制范围。
It researches displacement and dam body deformation extent. And it tries to find a control range for RCC gravity-arch dam displacement by comparing with other international projects.
应用平面有限元法对坝基处理前后坝体和坝基的变位和应力进行了计算和分析。
The plane FEM was used for analysing the displacements and stresses in the dam and the dam foundation before and after dam foundation treatment.
其原因是坝体和基岩黏滞系数较大，坝体自重引起向上游变位的时效变形需要较长时间才能稳定；
Because the viscous coefficients of the dam and foundation rock are great, the time-dependent deformation caused by the dam self-weight leads to the dam upstream deformation stabilize in a long time;
