| 中文摘要: |
| 本文以石门拱坝为例，说明基于原观资料进行拱坝及其基础的综合分析的方法。内容包括：在反演拟合渗透系数和坝与基岩接触面的抗拉强度参数的基础上，进行坝址区三维渗流场分析、拱坝与基础的三维线弹性、弹塑性力学分析，并用多种方法探求了拱坝抗滑稳定安全系数。 |
| 英文摘要: |
| The comprehensive FEM analysis for the Shimen arch dam and its abutment is carried out as an example to demonstrate the proposed method utilizing the monitoring data for calculation.Based on teh back analysis of permeability coefficient and tensile strength of the seam between dam and foundation,the 3-D seepage flow and elastoplastic FEM analysis of arch dam and its abutment are conducted.The safety factor against sliding of arch dam is determined using some different methods to verify the stability of the dam. |
