| 摘 要： | 本文在监测数据的基础上，采用时间序列和灰色系统方法，对长江三峡工程永久船闸二闸室至三闸首部分的中隔墩岩体变形规律及其发展趋势进行了预测研究。结果表明，垂直于闸室轴线的水平位移在开挖完成后基本处于稳定状态，平行于闸室轴线的水平位移总体向下游发展，而垂直方向的位移表现为先回弹、后发生沉降。 |

| Abstract: | This paper deals with the study on rock mass deformation of middle-isolated pier (MIP) of the second permanent shiplock. The time series analysis and grey system theory are used to predict the tendency of rock displacements of MIP based on in-situ measured data. The comprehensive results can be summarized as follows: (1) the horizontal displacement vertical to axial line of shiplock varies with the process of excavation, and is in steady state after excavation; (2) the horizontal displacement parallel to axial line of shiplock has the tendency of developing to downstream; and (3) the vertical resilient displacement occurs, and then subsidence slightly takes place in different parts of the middle-isolated pier. |
| Keywords: | the Three Gorges Project (TGP) middle-isolated pier (MIP) forecast |
