三峡水库应力场对水田坝断裂影响的数－力模型研究

Mathematic-mechanical Model Research on the Influence of Stress Field of Three Gorge Reservoir on the Shuitianba Fracture

水库蓄水后对库周环境有何影响，一直是三峡工程重点研究课题之一．近几年开展了多学科的研究，取得了一批国内外领先水平的科技成果，为三峡工程的决策提供了科学依据．三峡工程运行时必将对水田坝断裂产生影响，其影响程度如何？特别是峡谷型水库压应力场特征，是本文研究的主要问题．

The well-known Three Groge project has been executed recently. The effect after fullstorage in the reservoir on the surrounding circumstances is still one of the essential subjectsin this project. For the last several years,multiAiscipline researches have been developed anda number of achievements have been gained internally and abroad,which provide the scientific evidence for making decisions in Three Gorge constructions. The principal object in this paper is to research the influences of stress field,especially for hydraulic one,of Three Gorgereservoir on the Shuitianba fracture.
