摘要

针对三峡永久船闸中隔墩变形监测资料所反映出的几种典型变形规律，采用有限元数值分析和工程地质条件分析等研究手段进行了深入细致的分析得出以下结论：中隔墩岩体水平位移值的波动是由于临槽的不同步开挖引起的；第二闸室至第三闸室首的中隔墩向北“一边倒”是因为南北闸室地应力的差异和结构面的存在；中隔墩沿深度方向水平位移数值发生突变的原因是结构面的存在。并为研究岩土工程变形监测资料中的“个性问题”（或称异常情况）提供了一种有益的借鉴。

Abstract

The deformation monitoring data of the middle pier of the Three Gorges permanent shiplock reveals several interesting deformation phenomena. Conclusions and explanations are made concerning the phenomena

based on the finite element analysis and engineering geologic analysis. First

the fluctuation of the horizontal transformations can be attributed to the alternate excavation of the two neighboring shiplock rooms. In addition

the main reasons for the one-side-leaning phenomena in some places are the natural stress

which is not evenly distributed

and the presence of discontinuities. Lastly

the rockmass discontinuities result in the displacement breaks. A valuable reference for studying the ‘individual phenomena’ in geotechnical engineering is provided.
