链子崖危岩体稳定性研究

INVESTIGATION ON THE STABILITY OF LIANZI CLIFF DANGEROUS ROCK BODY ON CHANGJIANG RIVER

本文根据岩体力学的基本原则，并根据链子崖危岩体的特点，从地质条件、试验参数、力学机制和工程措施等四个方面进行系统阐述。在总结前人成果的基础上，进行了现场关键性问题的核实与补充，着重对危岩体形成的力学机理和破坏发展趋势及稳定性进行了具体深入分析，首次得到与实际调查情况相吻合的分析结果，并提出危岩体防治工作重点。

According to the basic principles of rock mass mechanics and the characteristics of Lianz Cliff dangerous rock mass , this paper is developed on geological conditions,test parameters, mechanisms and control measures. Based on study results of others, some key problems in situ are put forward and checked up. The mechanisms of the dangerous rock mass′ forming and the development of its break are analysed thoroughly and concretely. It is the first time that the analytical results are in accordance with the actual situation revealed by the investigation in situ. At last, the emphases of controlling engineering for the dangerous rock mass are put forward.
