三峡水利枢纽右岸大坝变形规律分析

Analysis on dam deformation law on right bank of TGP

结合长达6 a的观测资料,对长江三峡水利枢纽右岸大坝的水平位移、垂直位移、基础转动、基础地质缺陷部位的稳定性进行了综合分析,阐述了右岸大坝坝基及坝体的变形规律以及水库蓄水对其变形的影响,结果表明:三峡右岸大坝坝基坝体是稳定的,基础地质缺陷部位状态稳定,大坝的水平位移和垂直位移均较小,大坝变形受温度变化和水库蓄水影响明显。

Based on 6-year observation data,the comprehensive analysis on horizontal displacement,vertical displacement,foundation rotation,stability of geo-defect base is conducted and the deformation law of dam foundation in right bank and dam body as well as the influence of impoundment on the deformation are presented.The results show that the dam foundation and dam body of TGP on right bank are stable;the state of geo-defect base is also stable and the horizontal and vertical displacements of dam are small;the influences of temperature variation and impoundment on the dam deformation are obvious.
