| 摘 要： | 在对地应力系统研究的基础上,本文指出地应力场中的坝基岩体稳定分析应考虑计算块体侧面的阻滑力。本文就此提出了一个坝基岩体稳定分析的三维计算方法,并以长江葛洲坝工程坝基岩体为例进行计算。结果表明此稳定分析方法可进一步挖掘岩体稳定的潜力,提高安全系数。

| Abstract: | On the basis of systematic researches on the initial stress
of rockmass, the paper proposes that the frictional drag coming from the two sides of the rockblock should be taken into consideration for calculation in the stability analysis ofrockmass of the dam foundation, in a initial stress field. According to the above mentioned viewpoint, the paper has also suggested a three dimensional method which has been used for the stability analysis of rockmass of the dam foundation of Gezhouba project on the Yangtse River. The results showed that the frictional drag and the safety coefficient of rockmass of the dam foundation with this method could be increased. |
