| 摘 要： | 江垭水库蓄水后,水库坝区岩体出现了的抬升变形现象。本文分析了5种可能的导致抬升变形的因素,并认 为坝基深部承压热水含水层承压水头随水库水位升高而增大是导致抬升变形的控制因素,三维数值分析及岩石力学 模拟试验进一步验证了这一分析结果。本文还对今后坝区岩体抬升变形的观测和分析提出了建议。

| Abstract: | The rock mass lift phenomenon appears in the reservoir dam area after the water storage of Fiangya reservoir. The paper analyses 5 factors leading to rock mass lift deformation, considers that the artesian head increase of confined thermal aquifer in deep part of dam foundation along with reservoir water level raising is the control factor leading to lift deformation, the three - dimensional numerical value analysis and the rock mechanics simulation test proves this analysis result. The paper puts forward the proposition for observation and analysis of rock lift deformation in dam area from now. |
